NPK

Has anyone here been to a NPK's event?
They are going to be at the local dragstrip in June. They don't say where you be seated, or if you are free to walk around and look at the cars. Not paying that kind of money to be glued to a seat if I can't walk around. All that I know is a friend drove up to the last one here, he couldn't buy a ticket at the gate and turned around and drove back home. The bleachers weren't even full.
Would just like to know what your experience was if you have attended one of their events.
Thank you.
Been to two NPK events at Tucson dragway. There are very little if any restrictions there. We were in the pits till very late (early morning) hangin out with Jeff Lutz and the Bird brothers. And were free to walk around basically anywhere for the whole event.
