Someone built a house with a full concrete and stone foundation off of an I-5 onramp near me. Was pretty much hidden until it caught fire and took out the WSDOT land and a bunch of peoples back yards.The camps over here aren't nearly as sophisticated. Those Seattle camps are high class. I'd be proud to know that talented craftsmen with access to wood working tools were populating the streets.
Seattle FD respond to an average of 3 fires per day in homeless camps, a recent one started from a meth lab and exposed a safe with a few hundred thousand dollars in it. Will be fun when one takes out a section of I-5 or I-90,
