Do you think they saw your car? As in could tell the color and what not? I would stay clear of that place for a while. Just to be safe. If they ran after you then they had some bad intentions. A cool spot to smoke is not worth getting the shit kicked out of you or possibly killed.
I don't think they saw my license plate since there's basically no light and I didn't turn it on until I was away. But yeah, I won't go there again anytime soon.
