My worst fan experience was only 2 short years ago in Buffalo...

BG played poorly throughout the whole game with the Bulls but still led 17-13 late in the 4th quarter. Buffalo, who at this point had lost 18 games in a row and was a 21 pt underdog to BG, started a drive from their 20 yd line. The Bulls simply marched down the field like the BG defense didn't care (which I don't think they did anyway!)
I can't remember the Bulls RB that broke off a 27 yd td run with 1:25 left in the game. Our O got the ball back one more time and promptly lost 4 yards in 4 plays and gave it up on downs.
Watching the 5k Buffalo fans going wild at our expense was too much to bear. BTW, it started raining in the 2nd half. Walking out of the stadium I saw BG's Prez Dr Ribeau and shouted to him to fire Blackney.
The ultimate low happened only moments later when Buffalo fans (of all fans for cryin' out loud) started screaming at BG fans including yours truly. "Go back to Ohio you sh*%heads" and "BG sucks big time"!!...it was easliy a 15-20 minute walk from the stadium to the lots but it felt like a 5 hour walk. I was the last one left, in the pouring rain, in my parking lot, drinking a few Coors Lights thinking "This has to be the worst moment of my BG Football Life!" Yes, Chips fans, even worse than the infamous '94 fat punter game. Blackney resigned the next day and we skidded to our worst season since 1953 with a 2-9 mark, ending with a thrashing at the hands of the ut rockettes on national tv...
Also, losing to Kent in 1999 after the Flashes had lost 16 straight...Kent had a 17-0 lead less than 5 minutes into the game and led 31-6 early in the second. It was Kent's first victory since beating, you guessed it, BG at Dix stadium in '97 29-20.
And that's about all I have to say about that...
