parking somewhere that you know someone is the best choice. my last visit to the bay area i was going to be at my son's house in oakland. there's noting more useless than a trailer in oakland. thru the casita
forums i located a fellow casitian nearby that let me park in his yard for ten or so days. since i wasn't staying in the trailer it was no biggie. another security device you might consider is a "lo jack". these emit some sort of radio signal that allows the cops to locate a stolen hi $ car (trailer). it may be too pricy but then...
what's the chance of parking the casita
at the summer camp where you'll be working?
