We had a little bit of a conundrum about where to store the trailer. Our HOA is pretty strict about putting an old trailer in your driveway for an extended period of time, so we knew we had to do something. (Funny, though - the guy down the street NEVER mows his lawn and it's half dead and there are huge weeds growing up through the cracks of his driveway. Whatever.)
Anywho, we decided to rebuild the little fence between the house and the garage so that a section could be lifted out and the trailer pulled through. To conceal the trailer once it was in the backyard, we hung flags on a lattice and hung that from the breezeway. It has worked so far - no nasty letters from the HOA! My favorite part is the "Come and Take It" flag. A little Texas patriotism along with a little Chutzpah!
