Parking will be tough. Last time I was there, we were able to go to the top of the hill to park since motorhomes cant make it up the hill. Take a pit bike if you have one to ride to the top of the hill to the track. The probably should have taken part of the lower section of the track out so they could use that area for parking.
Nothing on the track is hard. Table tops and natural terrain. If there is a double, its not much, unless Scott has added some jumps. It is fast. One of the problems in the past, is that they could never disc deep enough, so the top was moist and nice, but about 6 inches down would be hard pack and slick. Hopefully Scott has some equipment there and helps with that problem. Parts of it is rocky.
One thing about it for sure, the 50, 65, and 85 gates are always full so Austin will have some full gates for sure.
It is tough to make a track great when you race it one weekend every couple years. So we will see how it turns out. I know people have been putting a lot of hours in getting the place ready for sure.
