Drive in & park what? They are not letting any cars inside the track unless you have preferred parking or a campsite. Cars are parking off site & people are taking shuttles into the track. It sounds pretty lame to me but it took some people 2 hrs to get in last year. The camping is packed & not much room for anything. Your best bet is to check out the corkscrew & walk over. The walk sucks now since they moved the bridge up the hill. You can try & get past the guy at the entrance to the campground if you want.
