No, Bryan, there's a restriction -- no 7-wheelers with three engines, one of which comes from a weed-whacker, and also absolutely no steam rollers! Other than that -- yup, all are welcome.
A little more serious response to the question -- The Hot Rod Top Speed Shootout has brought a whole bunch of cars to Maxton (that might otherwise never have been there). And this means that indeed, there are longer lines than we've come to enjoy. Bikes run just like always -- but don't be surprised when you arrive and see cars all over the damn pits, cars lined up in "pre-stage". There'll still be three lines in staging, still be Al the starter getting off racers as safely and fast as he can, still be course workers making sure the next few vehicles are ready to run as soon as the previous racer leaves so waiting is minimised.
Get your butt there and enjoy the weekend. The banquet -- hey, what other race event has bagpipe music to greet you when you arrive at the facility? We'll be there, maybe with bikes, maybe just to work. But we'll be there.
