You are searching for a red bison tube near the Beltline in Madison, WI. Do not search for this cache from the Beltline (Hwy 12/14/18!!!) On the other side of the fence is a popular Madison bicycle path with numerous access points from either end or from some of the businesses on Odana Rd.
Was hoping for a nice easy hide but found a spot that could be anywhere from easy to moderately difficult depending on experience or luck! Good luck!
Congratulations to Bill- on a quick FTF!!!
