So what have I learned? Well, don't set off your car alarm in Holmdel, New Jersey when a cop wakes you up in a Best Buy parking lot. And if you do, put the key in the ignition. First, find the key, of course. When an officer in Virginia Beach asks you sarcastically if you've ever killed someone, remember that sarcasm is a one-way street with keepers of the peace. People rarely hassle you in hospital parking lots, and sometimes you can borrow showers from Hotel chains. Marinas usually have showers, and some don't even make you want to take another one when you get out of the first one. When it's 87 degrees, leave the AC on at night in the jeep, or you will wake up feeling like you're crawling out of an egg. If you can stay up all night, you can grab a free night's sleep on a nearby beach, just pick a spot away from games of wiffle ball and put on a lot of sunscreen. When someone offers you a couch, a shower or a meal, say yes before they can even get the offer out. Maybe they were just trying to be nice but it will be too late by the time you've got that halfway decent night of shut-eye. And usually they are pretty cool. Set your cell phone alarm as loud as it will go, and put it as close to your head as possible. It's hard for a cell phone to wake you up at 4 a.m. for the fourth day in a row, so give it some help.
