The Bills RV lot has never been bad.
The lot opens at 8am, so most people party, cook and eat during the day on Saturday, meaning they're out early to get up and do it all again the next day.
It's a ton of fun to wander on Saturday, drink beer and make new friends! At night most make fires, sit out front and just hang, play cards, whatever. A few have outdoor TVs and watch the college games (and the Sunday late games - good people to know). Don't get me wrong, there are sometimes crews of bros partying, but everyone is mostly pretty respectful
Would also say the Bills do a good job of letting RVs take up a lot of space too, they don't try to cram a million in - which is funny, because they always sell out for the opener, you have to be there Friday night for the Sat AM gates. Plus as a HUGE bonus there's a "comfort station" with showers and toilet, thank the lord for indoor plumbing cause it's better to not fill up the RV toilet (no #2 on the RV!).
For me the RV thing was a "must do" for a loooong time and it has never disappointed!
