We need the Bengals to beat the Ravens this Sunday so why not make sure that the environment is as hostile as it can be. If you have the spare change and can't get tickets to Cleveland game (because the Steelers will sell that game out for the Browns) then hop on down to Cincy and support the Steelers!
I believe Steeler Nation is big enough to invade two stadiums on the same sunday. It would add to the legend that already is Steeler Nation. Also wear your Steeler gear so when the Ravens look up in the stands they should see black, gold, and orange in unison cheering for their demise. Don't worry that dirty feeling you receive for actually cheering for the Bengals will wear off by the Divisional playoff week.
If you are concerned about supporting the Bengals in anyway then rest assure that your support will further keep Mike Brown owning the Bengals and we know as long as he owns the Bengal they will be a treat. The enemy of my enemy is my friend and right now the Bengals are our friends.
