scott i think the spring thing at river rock is in May.  you should plan to be there.  assumeing i'm in the state (not TDY) i will be heading that way.  should be out of here some time this month, and just need to do a clutch job on the jeep and i'm ready.  i do have a pretty full schedule in May and have one TDY to Tinker that i have to go on but that is just a week, not sure of the dates yet.
