That sounds like a lot of fun. Sort of like a back yard bbq with a theme.both the bride and groom were wearing T-shirts and jeans. When we told our families, they insisted on having a pot-luck reception dinner. I provided the stereo and one of my brothers in law DJ'd all night. The "open bar" was a keg provided by a couple of other brothers in law. It was very simple, and great fun at minimal cost.
