Circuit of the America's (COA) S.E. Austin, desolate: HUGE property...most parking is far far away...have shuttles in downtown near convention center ($20) roundtrip (saw Taylor Swift Concert there-fabulous) (I saw a motorcycle race: study track layout on web before buying tickets: choose seats near the hot action bends / corners. I loved the smell of racing fuel exhaust...gunpowder ?
Ink black night (bring flashlights) remember where you parked your vehicle.
At the end of the show, you cover more turf walking than the exiting vehicles...thus, I recommend using the shuttle busses.
...buy COA event tickets far in advance from their website...
If you are from outside of town, how about staying for a while, and become a tourist. There are loads of free things to experience.
Y'all have a Blast !
