Re: Just a small gripe (for those looking for a tailgate)
I don't think you should completely give up on allowing people to join in on your tailgate from the forums, cause it sounds like it was just one bad experience out of a lot of good ones. Just maybe in the future, if you're dealing with someone you've never dealt with before tell them that if they want to join in to bring their own food (or drink, whatever) instead of relying on them to show up with money or a barter item for what you've already paid for.
Sorry you had a bad experience...sounds like you have a lot of fun more often than not though!
I particularly like the karma at the end of your story though. Sucks to be them stuck in the rain!
People assume that time is a strict progression of cause and effect, but actually from a non-linear non-subjective viewpoint it's more like a big ball of wibbly wobbly timey wimey...stuff.
