Parking Note to OP:
For over a generation, I’ve parked on Sheldon Road, near Abbott. I use the lots in front of the two Condos, but there are many alternates. It is a max 10 minute walk to the Stadium along the main drag- Abbott Road (which for security reasons you can’t drive all the way through, anyway.) You are surrounded by Bills’ tailgaters and Booze is close by at the corner, if you didn’t get it and Coffee at the Tim Horton’s 20 yards away- post game!
Also, waaaaaay easier to get in and out.
Oh yeah... ALWAYS dress for Cold from October on- no matter what the Temp says. This is an outdoor stadium, with cold wind. ?
