If you could go back in time, would you?

I wouldn't want to travel in time. I feel like it would be dangerous, and wrong. At the same time I am curious. If we could go back, kind of like a ghost of Christmas past kind of thing, where we couldn't physically intervene, I would. I'd like to attend an ancient pagan fire festival. Maybe visit the 1800s, I'm kind of in love with Poe, if you hadn't noticed. Oh, and I want to go back to Woodstock!
