The nicest wedding I went to was at a registry office followed by a back yard reception. It was so casual and you didn't lose the couple in all the usual formal wedding setups. The bride was eating hot dogs in her wedding gown but that's the relaxed sort of people they were. Everyone just wore neat casual. Dress pants and a shirt, no tie for men and summery sort of casual dresses for the girls. Was so nice to see everyone so relaxed.
