I noticed more odd drive by lookers at my equipment trailer the last couple of months. I only work in W Cobb and Paulding, but started locking the trimmers, truck, truck cap and sometimes running a cable around the back up mower on the trailer even in the best neighborhoods. It just depends on how big the job is and how long I'll be out of sight of the trailer. Seems like we are being cased a lot here in the metro. I even change the way I mow, so that I make a lap giving me a view of my trailer frequently when doing back yards. I hate it that we need to be that way in life. Good luck to you, hope you retrieve your equipment.
