Go for it!

I don't have many proposal suggestions other than some killer stories I've heard from my friends. Together they suggest a pattern: women love to be proposed to infront of huge crowds of total strangers. It takes a man to propose to a woman, but it takes QUITE a man to propose surrounded by a sea of unfamiliar faces.

And the tag line. She'll never forget it, so pick a good one.

Congratulations, and best wishes.
