do you sell beer?can you bring beer in at race events?

They do sell beer

And you cannot take in any container that is open even if it's a water bottle.

No you can't bring in your own beer. They have a bar right when you walk in that sells alcohol. You may only take in a soft sided cooler with no more than 6 cans in it. No glass is allowed. Also you can't take any beer you bought there out of the facility when the event is over. So finish it before you leave.
