Here are a few insider, expert tips about the killer ceremony:

The Chair Lowdown:

The ceremony will be held at 3pm at the Mississippi headwaters. It’s short; around 20 minutes. The ground is sandy with some grassy patches. We’ll ask everyone to form a semi-circle facing the birth place of the Mississippi river. There won’t be any chairs, but there are three benches that can accommodate three or four people each. If you can’t or don’t want to stand for 20 minutes, we suggest you grab one of the benches early or bring a folding chair.

Your Threads:

For the ceremony the attire will be casual. What does that mean: You can leave the tie at home, but you’ll have to change out of your swimming trunks before 3pm rolls around. No hairy, bare chests please!
