I used to go to YMCA Camp Weona as a child and as a young adult (camper and counselor respectively). The land for the camp was originally seneca (i believe... its been a while) indian land, which was donated to the buffalo Y. There are a lot of spooky stories there, however none spooks me more than the one that can't even be explained:
anyhow, as you walk down the main road to one of the villages with cabins, you go around a bend and up a small hill. At the top of the hill is the village and there's a light on a lightpole. Because of the mountains (the camp is in gainesville, ny), that small hill, and the light, there's a fog that's created. Anyways, none of the dozens of dead indian/lost camper/attica escape stories got to me... That 100 feet from complete pitch black to the top of the hill where i could see the cabins was and still is the scariest place i've ever been to in my entire life. It's the same in the daylight. It's scary to me, its scary to everyone who's ever been there. The feeling i get is that of an overwelming feeling that someone is watching me and walking behind me. It's scary with my eyes open, with them shut, with a flashlight, without one. It's scary alone and its scary with people. It's just scary and i can't explain why. I'm sure someone can second my thought if they've ever been to weona.
now on with my ringing endorsement of the place: send your kids to YMCA camp weona... I grew up there and i love it to this day.
edit: now that i have brought this subject up, if there are any other weona alumni on the wall right now, send me a PM... i'd love to share some more stories (there's more where that one came from)
