I would try a store that sells cards and gift wraps that include bags...I've seen clear bags there. The cooler looks like a small lunch bag size to me. I know some people that are going, I will ask them and get back to you.
You should be able to buy the little soft-sided coolers at Walmart, they look more like little lunch boxes due to the size. As for the bags, normally if you buy something from the team vendor trucks you will get a bag. I'm not sure if you can buy them. We are headed down to the race as well and it will be the first for my husband. I hope the weather cooperates!

Come on now any dedicated<;O) NASCAR Fan would hit the hardware store, get some 6 mil plastic sheeting and a roll of Duct tape and Make a bag...
If Ya need a clear cooler just sandwich some layers of bubble wrap inside another of the same thing.
