California ProKart Challenge

Pre-Entry Cutoff for Monterey is Tonight!
Monday, 28 August 2017 08:44
I know everyone is busy getting their SuperNats entries in, but don't forget Round 5 of the ProKart Challenge is this weekend at the Monterey Bay Karter's track in Marina and the cutoff to pre-enter on MSR is tonight at midnight (walk-up entries are more expensive!).  Full event details are available on the Monterey Event Page and you can still reserve a pit or camping spot at the SKUSA Store.  The weather will be mild, in the mid to high 70's and Albacore Tuna is in season at many popular seafood restaurants in the area - which means you should invite your friends, family and significant other and buy them a pit pass.
