Since we can't seem to stop the opponent fans from getting into the stadium, then we need to make sure their stay is a miserable one and they leave pissed and dejected.
The azz hole owner of the seats in front of mine always puts his tix up for whoever pays the most $$$
He shows up maybe twice a year. The 2 Bear fans that that sat there yesterday left halfway through the 4th quarter thanks to my spilled beer under their seats and my constant in-their-ear LUUUUUKKKEE. I don't mind visiting teams fans coming into our house but when they try to take over the whole place it just pisses me off and I will make their visit as legally uncomfortable as possible
