Take your cooler!
It's happened again; Seth posts about something that just happened to me.
If it were really a security issue, they'd have to enforce it completely. If it's just a silly policy that someone dreamed up one day, it's sure to annoy people. Because it's irrational. Because it's not enforced in a way that makes sense.
I went to the Braves game yesterday. They lost, but it's always fun getting an Americana fix. We baked out in the cheap seats (I told my kids, I'm never paying $30 extra per seat for shade goddamit) but Tara had a brainwave and suggested we take a cooler. I would never have thought of it - I assumed they'd want to make megabucks at the concession stands.
But sure enough, you CAN take coolers into Turner Field. On their website, they have rules buried deep somewhere. Basically, no hard-sided coolers, no cans, no glass bottles. So we took our soft-sided over the shoulder cooler filled with ice, plastic water bottles, gatorade and snacks.
Unbelievably, they let it in after checking it out. There was a large trashcan full of cans that people couldnt bring in.
Why? I don't get it. I thought perhaps it was to stop people throwing them at the players? But you can buy cans and glass bottles of beer inside the field. So why??
I'm not complaining, obviously. We must have drunk 15 bottles between us during the game. And they weren't $4.25 a bottle 
Even funnier, on the way in there were many people selling "ice cold water, $1 a bottle, take it into the game". One family didn't buy because they were convinced it was a scam; "We won't be able to take it inside".
Anyway, it's a handy tip. Check if your next sporting event allows soft-sided coolers.
