I love picnicing in cemetaries. I did that a lot in my college days. My favorite place in college town was the cemetary on a hill facing west for the sunsets (appropriate). There was a great stone sarcofogus that made a wonderful table. I once did a double date there with my roomie, wine, cheese, grapes.
And just on a side note, small town cemetaries at night are great places for "outdoor romance". You aren't likely to be disturbed and neither are the residents.
I love cemetaries. And I mean no disrespect to the dead. May they rest in peace.
