I really don't have any sympathy for people that get bikes stolen "out of the front yard" or "right off the porch." In today's world you've got to be more careful, and don't make the job easier than it needs to be for potential theives. A lot of those crimes are just crimes of oppurtunity, meaning they'd steal it off the porch, but not out of the garage locked up. People that leave valuables outside should be prepared to eventually lose them, sad but true. Thats why I keep all my bikes/tools/cars in the garage, with the door locked.
Grow a brain morans, lock up your stuff! Sort of hope they get their bikes back, if not learn something from this!
*apoligies if the bikes were locked up in the front yard, but from the sound of it they were just sitting there.
