always found 6-8 hours before kick off is a good rule of thumb. can experience it all without feeling drawn out, but I usually have the children in tow; prob’ different for you.
good luck brother, hope you enjoy it. there isn’t a better tailgating than Buffalo, obviously lol
if you ever get a chance to attend a game in KC or NOLA, they’re the next best option!
enjoy the game, may it be a win all around for your first visit!
