I will be going there as offen as I posibly can this fall. DB_1 started a thread called "Not the Offical Truckhaven Thread" about this same question. There was no 100% garuntie (SP), but I would be willing to bet there will be atleast two runs before the MLK weekend event.
Oh, seeing as the temp is starting to go down alittle bit. If you want to get together for a THaven run let me know. I will be more than happy to take a trip out there for a day.
