I just called the letchworth state park to reserve the north lean to on the letchworth trail. I have been going there for several years and never had anyone tell me I had to sleep in the lean to. She told me no tents, I said fine then she says no hammocks either. What is happening? In fact last year they made a mistake with our reservation and people were already at the lean to so they asked if we had tents to stay in since we couldn't use the lean to. I know it won't be a problem since we hardly ever see anyone back there anyway, but this is something new.
