I was recently looking at a challenge cache that you needed to find a cache with all the colors of the rainbow. There seemed to be lots of caches with all the other colors except indigo.
The posted coordinate's will take you to 2 large beacons, just outside the baseball field. One has a silver backing, will call it the scoreboard. The other beacon is painted mostly green, will call it the billboard. In order to find the final, you will need to do some quick, simple math.
To find the final go to N44 48.AAA, W093 07.BBB
How many stanchions are holding up the green billboard X 135 = AAA
How many stanchions are holding up the scoreboard X 214 = BBB
Good parking can be had right on Northview Park Rd. and it will be a short walk to both stages. The cache is located in Wondering Walk Park
