I think NASA is charging $285 for a two day event. They had pretty poor turnout the first year at ORP so I don't know if they will make it to ORP again next year. It was nice to have so much room on the track though.Yeah I saw ORP, thats my favorite track. I normally run advanced group on HDPE's and prefer open passing as long as its open passing with point by's and not overtaking. I will like their page and maybe see you out there.
