I've been fairly paranoid about driving across the country towing my enclosed trailer and spending nights in New York, Illinois or Iowa, etc., but luckily, without incident. I have a big cable and lock I sometimes thread thru my trailer wheels and the frame to slow down would-be thieves. What I really wanted to do was to get my vinyl graphics guy to decorate the whole trailer with skunks and minks with the slogan "Small Stinky Animals -- We Show the Best and Gut the Rest," as a deterrent, but my wife wouldn't let me. Would have been more appropriate if I had been racing two-stokes!
