I live 50 miles from UF and for the last 30 years have been to every UK game but one at The O'Dome. but am lucky to have Bull Gator friends that always host me for UK?
I imagine there will lots of tickets, even though we will still be number 1 ( I hope) but UF is off and the crowds dwindle quickly when they aren't winning....see " football school"
If you are the nervous type then go ahead and get a ticket, but I would be safe IMO to say you will find plenty of tickets at a very fair price. All around the O Dome exterior. If you don't mind missing the first few minutes, you could get a steal at two or three minutes after tipoff.
There are many good seats in the first several rows of the of second levell too, since it's a small place.
Go cats.
