I went to the RGV this year and it was our first time going, it was ran very well and there were a lot of families and kids there. We only saw one burn out that wasn't on the track and they escorted those guys out super fast.
We have been to Houston several years in a row, 2010 to 2012 were out of hand, but I must give them props as both Houston events we went to this year were very well organized. They had more than enough security and they finally blocked off the entire road back from the track so racers could get to and from the track very efficiently.
We are looking forward to this LS1Truck event as well!
