Lone Star Park, Arlington
A BEAUTIFUL race park with an even more impressive simultcast building. Prices for food can be a pretty penny but find a night where there are $1 drinks or cheap beer. The night we went even had live music in between the races. As long as you don't gamble away your vacation money then it really is a nice night out.
General Parking $3.00
There are nicer seats upstairs but you pay more for those. I actually had more fun being on the general admission grounds and listening to the music, walking around, etc.
