I have been tailgating on & off since the early 70's at Shea Stadium for NY Jet games. It is fun to pack the SUV with all you need & cook on the road. I must say over all the years I have never really forgotten anything big or small.....use my lists LOL
I started with a little Hibacchi, cooler & BW TV.
Then a small portable gas grill, Cooler & BW TV
Now I have a hitch mount gasser, Fryer, Small Charcoal grill & butane stove, Two coolers, & color TV with built-in DVD. Heaters & tents. I also tailgated at a Cards BB game at Citi field once.
My bucket list is to boat-gate at Citi field for a Cards game someday.
(but I need the boat)
At one time I would boat gate at block island
I have tailgated at Genesis Concerts but that is mostly adult drinks & sandwiches
My wife cooks as much or more on the grills at home but I take over on the road lol
Its funny in those early days at shea there would only be a handful of us early at games....boy that has changed
