I'm not sure exactly what time I'm going. I checked the Z Nationals site and they don't say exactly what time the events get started on Saturday.
Unless I hear otherwise, I'm going to head over there mid to late morning (10 or 11ish). I think I'll be riding out with another local Z buddy (since I'm Z-less - or at least running Z-less - at the moment). Are you heading out? Want to get a small caravan together to head down I-20?
