The class is M-Th, so my plan would be to drive over from Red Bluff after the class ends, crash somewhere for the night and leave my truck at the hotel while I do the ride. I plan to finish in 2 days (one night on the road) and would probably stay at the same place after so I can rest before the drive home (3+ hours) which I wouldn't want to do right after the ride.
This would give me plenty of time for the riding and to check out the area. I'm not sure about the terrain, but it looks pretty level. If that's the case and I do the whole 30+ in one day then it will turn into a couple of day trips from the hotel. I would still ride fully loaded and can use it as a chance to check out the bags and get used to the balance of a loaded bike.
