1. Find a suitable tent mate (raises hand)
2. Pack lightly. You'll have to drag your suitcase across the camp every morning and afternoon.
3. Solar charger (for phone + computer), coffee mug (the cups they have are tiny), etc. Think, "I am backpacking for a week. What do I need?" Don't forget ear plugs (hearos)!!!
4. Choose your tent location (when you get to San Francisco) wisely. You get a letter/number combination (like J21). The numbers indicate the distance from the first tent, but turn over half-way (so that the last number is right next to the first one). The letters are the distance from the trucks.
If you want peace and quiet, choose the highest letter and the middle number. You'll have to walk the farthest to the truck and the mess hall, but there will be the least noise. If you want convenience, go for A1, but accept the fact that everybody will walk past your tent.
5. The tents fit a queen size mattress, or two twins. Go for a low-rise mattress (less space, less bouncy) with a battery inflater
6. For crying out loud, get yourself tire liners! Otherwise you'll get silly changing tires. In the same vein, make sure you know how to change a tire quickly. Unless you like being the damsel in distress at the side of the road
7. If you don't feel like riding anymore, don't force it. The bus that sweeps at the end of the day is waiting for you, and you don't want injury before the ride is over.
8. Do yourself a favor and "princess" it once. Get a hotel reservation for one night and sleep in a real bed with real sheets, room service, and a real TV. Preferably do it on the night in Paso Robles: the city has tons of hotel rooms near the camp, while the camp itself is right next to the freeway.
9. Don't. Forget. Your. Camera.
