We had a "surprise" wedding. Invited @ 85 people to a pool party at her parents place. Beer, BBQ and boiled shrimp. Told the entourage we had an announcement, we were getting married. They asked when? The preacher emerged and said "right now"
No pressure, no gifts, no stress. Total cost? @ $2500.
That was June of 1991, 2 days after my 727 FE ride. Still happily married.
