1) When the weather is nice, cook low and camp high. Sure, staying at a shelter with water nearby is very nice, but you can miss out on a lot of great campsites when you constrain yourself to camping with water. Instead, cook at a water source, fill up on h2o, and camp up high with a view.
2) Do a "nero" instead of a zero day in town. A lot of time, I would push hard to get to town, then be so tired that I would take a day off in town. Instead, camp out a mile or two away from town. Then, in the morning, walk in and take a virtual zero day. This way, you only have to pay for lodging for one night. If you do this, take a lazy day on the second day and just hike a few miles out of town.
3) Carry a NASCAR baseball hat. It makes hitchhiking in the "red" states a lot easier. But whatever you do, don't mention Jeff Gordon.
