TL;DR: Hike to a small cache along the shore of Boston Lot Lake. Make note of the letter inside. Possibly a difficult find.
I chose this location after finding it to be a great spot to relax and throw sticks in the water for my dog to swim after. It is a hidden little spot with good views around the lake. There is a resident beaver in the "bay" to the left, and I once watched a turtle laying eggs near shore as I ate blueberries, which are plentiful. It's worth a visit.
Bonus Cache: This is part of a series of caches, each of which contains a letter tile from the world's most popular word game. Take note of the letter associated with this cache if you would also like to solve the puzzle in the bonus cache, GC9YGNA Drawing a Blank.
Caution: Actually there's not much to caution about here. Tick risk is low. A small amount of rocky off-trail hiking at the very end.
Container: The cache is a small, rectangular, heavily camoed food storage container.
Hide: This could be a difficult find because of the number of possible hiding places, but then again it could be fun if you enjoy the hunt. If you get frustrated, the hint should help a lot.
Access: There are several ways to access the trails in these woods. See the waypoints for suggested starting points for this particular cache. Maintained hiking trails will bring you within about 200' of the cache, followed by a woods walk on a faint path to a nice spot along the shore. The Trails map (premium feature) in the geocaching app shows most of the trails in this area. The hide is accessible in winter.
