CarLiving.com – the survival guide to living in a vehicleI did this for about 2 weeks when I lived in Austin and I have to say it wasn’t too bad. A liberating experience in many ways, but of course it sucked to try to find places to take a shower. — One place I found though that was almost free was McKinney Falls State Park. If you go during the daytime it only costs $2 to get in the gate and then you can take a shower w/o any problems. (of course the signs says the showers are only for folks who are camping but there is no way that they would know)
