A quick note. If anyone ever finds themselves at Gillette for a game in the future, I learned somethung early Sunday morning, Park in the upper lot at Americas Best Value Inn on RT. 1 ($20 for upper lot) and tell the attendant you are going to "The Cave" which is a couple shipping containers all outfitted for tailgating. 1 Container has full bar, TV, 20' shuffle board table and a Golden Tee video arcade game. The other container is where they keep all the grills, Blackstone griddles tables and chairs. There is a port-o-potty that gets dropped off every Saturday before a Pats home game. Just bring your own beer etc, and your own food, although there is planty there if you just want to grab a dog or a burger, or a slice of pizza.
The conatiners are owned in part by a friend of mine( former boss) who has been a season ticket holder since Gilette opened. There is a donation jar in front if you want to contribute.
Be warned tho, its about a a mile from the stadium so it's a decent uphill stroll. And by the time you get back after the game, everything is packed up and locked up, including the portojohn.
