The cache is NOT at the posted coordinates! The posted coordinates will lead you to a spot near the Veteran's Memorial Park. There you will find some signs, including one with a map of the Napa Valley Vine Trail. Use the clues on those signs, and what you see near and in the park, and in the write up below to figure out the final coordinates. The cache is a short walk away on a paved pathway.
Welcome to the Vine Trail!
The Napa Valley Vine Trail is a 47-mile walking/biking trail system connecting the entire Napa Valley. It starts at the Vallejo Ferry Terminal and winds its way north to Calistoga along Hwy 29. The trail is organized into 10 sections, each named for the city or AVA (American Viticultural Area) region it passes through: Vallejo, American Canyon, Los Carneros, City of Napa/Coombsville, Oak Knoll District, Yountville, Oakville, Rutherford, St. Helena, and Calistoga.
The Vine Trail was begun in 2008; only some sections are currently complete. The most notably complete section is from Kennedy Park in Napa to Yountville, a stretch of 12.5 miles. The entire project is estimated to cost about $50 million. Fundraising events and capital donations will provide some of the funding. To date, $12 million in federal and state funds have been appropriated.
Answer the questions to come up with the final coordinates:
N 38 0A.BCD W 122 EF.GHJ
A= The number of wooden benches you can see from the posted coordinates, scattered around the park.
B= The sum of the digits in the amount of federal and state funds that have been raised for the Vine trail so far
C= The Oak Knoll District AVA is the ___ Section of the Vine Trail as you head North from the beginning of the trail
D & E= This part of the Vine Trail follows an historic route, and a state highway. Historic Route #____ minus State Hwy #____ = D E
F= At the posted coordinates, you see a Trail Boundary Vine Trail Mile Marker. F= ____ miles
G= How many red stars are there on the sign at the posted coordinates?
H & J= The last two digits of the utility power pole number you can see at the posted coordinates (NOT the maintenance tag #)
