I can't wait to college football season to throw my first Tailgate party of the year.
I've never tailgated but it sounds like a lot of fun
My first tailgate party was at a concert. It was wild. We never made it into the concert.
I thought tailgating was just for football games.  Are they all similar?
Nope, all sporting events and also concerts. You can have a tailgate party in any parking lots at stadiums and arenas
Is food common at concert tailgates?
Some food but I just drink. Tailgate parties last all day at sporting events. 
Are you going to BBQ at your first college tailgate?
Not this year. My wife is pregnant so it's going to be low key. I will be enjoying the consumption of alcoholic beverages and she will be having a soda and sandwich. 
That's too bad but congrats on the baby.  Next year you'll be a troop of three
