I was just out running in my neighborhood when this black SUV was driving around the neighborhood REALLY slowly mabye 5mph or so. It was just really suspicious and all the windows were tinted. I've ran around my neghborhood a thousand times and I know everyone's cars, whoever was driving definitely wasn't from around here. I didn't really think much of it at all though until about the second time it passed me but instead of driving by it STOPPED right next to where I was running and just sat there for a second or two and then peeled out really fast and stopped mabye 200 feet away, then just kept driving slowly again. I was foolish and should have ran home at this point, but I thought they were gone and just kept running... about 5 minutes later I see headlights coming from behind me and I glance over my shoulder and see the same SUV again, going the same slow speed. It again stopped next to me and peeled out, now at this point I was getting pretty nervous. I stayed calm though and kept running at my normal pace until the SUV was out of sight, as soon as it was out of sight I took off running the other direction towards my house and called 911 and told them everything and how it was really suspicious and bizarre... they said they would send out an officer to drive around my subdivision and check things out. If a bunch of dudes got out of the car or something I really have no idea what I would have done, every scenario was going through my head though and this was the first time I really wish I had a CWP, but it was stupid of me to not even bring a cell phone. The second I got in the door I went and unlocked my safe "just in case" and then I called 911. And the worst part is I didn't get to finish my run, but I guess sprinting half a mile to get back home made up for it .
