This is a challenge caches and the final IS at the posted coordinates. You can sign the log any time, but cannot claim the find until you have met the challenge as listed below. There is no parking along Marksheffel Rd so please see the parking waypoints. There is sidewalk the whole way so walking or biking it is great.

The Challenge
You must find a multicache for each day of one calendar month. The multis can be found in any year and are cumulative. Please note that February 29 is included in the grid but is optional. You do not need a find on February 29 to use that month to qualify. The checker will show your progress.
There may be other versions of this challenge but the first one that I saw was philbeer's Challenge - Month of Multi's, GC8TM52.
