Yep. I believe someone I work with is tilting nails under my tires so I get a flat as I back out of the parking space. I literally walk around the car and check for this each day after work but forgot yesterday and once again had a flat. I want to set up a camera but not sure what that involves and know I would need to get the permission of the work place. So I thought maybe I would open this up to ideas on how to solve the problem. I have tried to change the place where I park and it doesn't seem to help. Very frustrating. Ideas?
