Carpediem- Are you talking about coming down this week for regular Sat and Tue night racing? If so, I can answer your questions.
Yes, there is a "load in" time on the schedule. That's when they open the gate to cross the track. It's way easier to get stuff across then. I use a wagon, and getting that over the bridge isn't fun.
The spots are first come, first served. It usually isn't a problem on regular race days. There's a big tent with chairs too. My crew and I usually grab a few chairs and set up there to try and stay out of the sun.
What category will you be racing on Sat? I'll be in the 55+ field.
