Hi all,,, I am going to the St. Louis SX and wanted to get some info on the pits...I usually go to indy where there is no "real" pits. I have been to nationals where you buy your pit pass at the stands. Can someone please tell me how the pits in St. Louis work? When do I buy the pit passes, what are the hours, are the pitts similiar to the nationals where you have all the riders, etc all there and you can roam freely once in? Thanks!
