Good thing it worked out. I know they are not cheap, but for my place(1500+ foot driveway) i plan on a remote operated gate. Gates are a great first line of defense. Most guys like that would have driven on to a place with easier access when confronted with a gate. Of course there are dozens of other things that can be done(alarms,dogs,geese,cameras,booby traps /forums/images/graemlins/laugh.gif...etc) but difficult accessibility is at the top of the list.
