re: For those that have been to Omaha?

I've been six times.

You can get tickets outside the gate for less than from any of the ticket brokers.

Know how to negotiate going-in.

It's the championship game, or now the championship series, where you had better plan ahead and start buying passes from eliminated teams' fans before they leave or sell to scalpers ... that's where it gets dicey.

You can wear whatever you want to wear, Ole Miss clothes or whatever, I've never had a problem with buying tickets outside the gate from whomever, especially fellow SEC fans.
