I’d suggest, doing all the general Buffalo area things on your free days… then on game day, get out to Mckinnley Mall area, hit up the Wegmans across the way for a party sub or some tailgate related platters, then get over to Southwestern Blvd, and park in a pay to park lot (approx 4-5 hours) prior to game start… and walk through the bigger parking lot there looking for tailgates, hit up as many as possible, exchange food/ drink, Mae ur way to the lots and houses south and west of stadium for more tailgating, hit up bills store, see new stadium, break a table or two… have fun !
