If you ever need a place to park at the northwest end of GBP, I live in the apartments on Barker Clodine located here: http://maps.google.c...N 95°41'7.00"W
You can probably discreetly park in the apartment complex office parking lot. I do not think they really watch what goes on outside. They also do not have any signs advocating that they tow vehicles that are not doing business there.
I know at the last big smiley a bunch of you parked at the end of the road.....there really isn't much proper parking down there so I would suggest you avoid that area to park in. Being a policeman myself one can fairly easily justify towing a car if it is obstructing traffic.......
That end can just get too congested and it's difficult to turn around, tons of pedestrian/bicycle traffic, etc. I think it will save you a possible headache later.
What four paw said is exactly correct, if it legally parked, 18 inches to the curb, same direction of traffic, etc. There is nothing a citizen can do about it. That being said, they can still do crap to your car that can make a minor hassle even worse....as someone else suggested, just park a little further down the road.
I will even happily let people into my complex to park there for larger numbers of vehicles that need to go into the park....heck I will probably go with you!
