I had a trimmer stolen off of my open trailer (at that time) and I was pissed and yes a weird feeling of security or lack of. I thought they would be back to finish the job the next night. Sure enough they were back, to their surprise I waited for hours in the dark and when I came out with 8 iron in hand swinging! the kid about sh!t a brick. I never saw some one pedal a bike so fast in my life. After that I used a very thick cable winding it through every piece of equipment on there. Never any problems after that. As the economy gets worse, I bet thefts will be on the rise.
