I think you should write a book, but don't go through the vanity press ripoff. Publish it yourself.
I have known people who live out of a van/truck camper until cops realize what's going on. They will harass you to no end. The tickets are expensive. The days of " Just move on." are over.
That said, in most counties, there is nowhere to park a vechicle overnight. We need to desiginate areas, in commercial areas, where people can legally sleep.
They have pretty much made it illegial to sleep Anywhere, without paying. Even Parks have time restrictions. I'm ashamed of what America has become.
If Jesus Christ reappeared, he would be hit with multiple municipal fines within a few days. It's just not right.
(If I seem mad-- I am. I had a friend who tried to live in the back of his truck, and take showers at a local gym. Cops harassed him nightly. Once the gym found out he was just using the showers--they made his life difficult. The one slime ball manager would time his workouts in order to use the facilities. Wonderful world we've got? Oh--yea, he was doing non-union construction. The last thing he wanted to do was workout at 6:30 a.m. in order to take a shower.)
