Here's yet another way our open space and parks are used: A Pow Wow. This one was in Pomfret, where I was letterboxing, geocaching, leaf-peaking, and meeting up with a friend (who tipped me off to the Pow Wow). There was a roped-off circle where various dancing and drumming and such was taking place, and an outer circle of vendors selling things like Buffalo Burgers, jewelry, and animal pelts. I very nearly bought an entire beaver pelt, including the tail, for $35. But I couldn't imagine what I would do with it, and settled for an amazingly soft rabbit pelt for $7 for my daughter.
There are schedules of pow wows available online, like this one for New England. In some ways my favorite part was simply hearing the drums and flute in the background as I walked through the forest approaching the pow wow, because it felt timeless.
