You are looking for a monument in Barfield Crescent Park. Barfield-Crescent Park, located off Barfield-Crescent Road near U.S. 231 South (Shelbyville Highway) is one of Murfreesboro's newest parks. It includes over 300 acres of full-service venue, walking trails and a wilderness area.
If you would like the more accurate coordinates for the monument provided by the American Congress on Surveying and Mapping, they are:
N 35d 47' 02.49900"
W 86d 24' 53.97678"
The Center of Population Project
In a project co-sponsored by NOAA's National Ocean Service (NOS), the Census Bureau, and the American Congress on Surveying and Mapping (ACSM), many states are in the process of officially monumenting their Year 2000 Center of Population by setting commemorative markers. Most recently, Missouri, New Jersey and Washington have set and performed GPS observations of their 2000 Census Center of Population monuments. A number of states have now set such markers. In a cooperative effort, the Census Bureau provides the location of the state population centers, and NOS provides the guidelines for placement of the marker. ACSM coordinates the monument setting and observation performed by state professional surveyors. This is an excellent example of what collaboration between the private sector and Federal, state and local governement surveying and mapping professionals can achieve. It is expected that all state Center of Population sites will be included in NOAA's National Spatial Reference System, which will allow surveyors and others to utilize the markers.

Site selection and mark setting requirements for Center of Population Monuments:
The site selection should conform to the following criteria as much as possible:
1. As close to the computed coordinate as possible
2. A "GPS-able" site (e.g., clear of obstructions 15° above the horizon)
3. Located on a publicly accessible site (e.g., town park, road right of way, etc.)
Once a suitable location has been selected for the Center Station, the mark should be set in accordance with "General Specifications for Aeronautical Surveys," Attachment 7-9 as listed at (visit link)
Given the unique nature of this project, it is recommended that a special commemorative mark be produced of at least 8" in diameter. The mark can have whatever logo or design the organizing committee decides. NSPS and Berntsen International www.berntsen.com have designed a disk that can be used. The design and contact information is provided in the attached information package. The costs of the survey mark will be the responsibility of the State Survey Society/Association
GPS equipment and observation requirements
All observations must be performed using dual-frequency, full-wavelength GPS receivers. All antennas must be of a make and model that have been calibrated by NGS - see: (visit link)
Fixed height GPS tripods (quadpods) are highly recommended, but not required. If fixed height poles are not used, special effort should be made to ensure an accurate height of the GPS antenna is measured at the start and end of each session. These measurements should be recorded and diagramed on the "Illustration for Antenna Height Measurements" page of the GPS observation log sheet describes below.
GPS network design will include 3 CORS and/or HARN stations. If there are 3 CORS within 300 km, then there is no requirement for connections to HARN stations. However, it is recommended that at least 1 HARN and 1 North American Datum of 1988 (NAVD 88) bench mark (BM) published by NGS and within 50 km also be observed. If convenient the HARN station and the BM should be the same station.
GPS observation at the Center Station will consist of 3 each 5.5 hour sessions, with the start time of one session offset from the other 2 by at least 4 hours. Sessions do not all need to be on separate days. (i.e., 2 sessions can be on the same day).
If there are not 3 CORS within 300 km, then the observations at the HARN station(s) should be coincident with all Center Station observations. If a separate BM tie is performed it should be at least a single 4 hour session coincident with the observations at the Center Station. It is recommended but not required that there be 2 each 4 hours sessions to the BM. A separate NGS GPS observation log sheet, visibility obstruction diagram and station description/recovery form must be completed for each station in the project. GPS observation log sheets must be completed for each session. Copies of all forms can be found at: (visit link)
Logging this cache:
To log this cache, stand at the monument and take a sighting on the tallest tree at a heading of 310 degrees. Walk to that tree, about 380', and you will find the log in a 35mm film cannister. On the cache page, log the distance from your home coordinates to the monument. Photos showing you and your GPSr are welcome, but please do not post photos showing the monument on the cache page. The monument is such a nice surprise that I don't want that lost by seeing it ahead of time. I have left a Gold Dollar for the First To Find.
