1. All in, about $280 for a family of four, with 8th row end zone tix (see below). We brought our own drinks and munchies (bottled/canned drinks and alcohol is prohibited, but bottled water and small boxed juice drinks, plus your own munchies, is okay).
2. No, never felt threatened, except by very real possibility of having beer spilled on my head. A lot of fans were waving their beer bottles (plastic) around as they raised their arms to cheer. One guy nearby did get a drenching, but he was so inebriated, I don't think he noticed it.
3. No, no security related incidents anywhere in the stadium or in our section. A lot of very drunk fans, but no hostile ones. The mood may have been a *lot* different if the Bengals were losing, especially to Carson Palmer's Raiders.
4. I'd say 8 on a scale of 10. Well over half of them were far past legal driving limit, drinking half a dozen or more beers. Some of them could barely walk by the end of the game. Even those who appeared to be the designated drivers had a few too many. I think, apart from one couple and their son, we were the only ones not drinking beer.

5. No, not a suitable environment for toddlers and even young kids with the behavior and language. There were a few kids in our section with their dad and/or mom & dad, and one kid (about 7 or 8 years old) kept closing his ears. Families are better off taking less populated balcony seats. The end-zone section is probably one of the rowdiest. A number of the adult fans (without kids) were obviously regulars to each game, already knowing each other and leading the drunken fight songs. My advice: Leave your kids at home.
6. a) If home team is winning, you're welcome to be there in humiliation.
6. b) If the home team is losing, and you're rubbing it in, you might be asking for it.
As it was, Carson Palmer was the one being humiliated, so everybody got along. I (and a few Bengals fans) high-fived the Raiders fans on Janikowski's 55-yard FG which looked like it could have been good from 70 (no kidding, it was up near flag level, way over the crossbars). The Raiders fans, for the most part, sat in stunned silence for most of the game, with the Bengals in control all game.
