Yup, done that forever even though I haven't played since little league. Have a hard ball too with them. When I got searched by LE a few years back, the cop didn't think twice about them being there.
Ps. If you are the pickup truck driver two years ago who boxed me in when I was parked under the I678 last year such that I had to go thru my rear hatch, pull down my rear seats to get into passenger compartment, climb over my front seats to get into the drivers seat, I'm the one who left the note on your window, calling you a shit head. However, I don't know who put the black, 3 inch lag bolts positioned under your front and rear tires.
At least I was lucky that my mirrors were at a different height than yours so I could actually carefully back out of my spot w/o them getting damaged.
