If you could...

Reading through this thread I thought for sure someone would say they'd want to visit the "grassy knoll".

I think I would want to visit a victorian household and just see how they really lived for a day. Especially since I could come home after 24 hours to superior medicine and plumbing.

Or since this is a magical hypothetical I think I might want to witness the day the very first of our ancestors experienced humanity.
