This cache is located just off one of the paths in Tinker Nature Park. You are looking for a small bison tube hidden inside another container. There is no room for exchange items, and you will need your own pen or pencil to sign the log. There is no poison ivy in the immediate area of the cache, but it's a good idea to keep an eye out for it whenever you are off the path. Enjoy your walk in the park!
While you are at Tinker, you may want to check out the fairy houses along the main perimeter trail, starting near the playground and continuing around the southeastern corner of the park. Unfortunately dogs are not permitted in the park so geopups will have to skip this one!
Congrats to Team Daisydog for FTF! Love your alphabet caches!
