That's a good question GD.
For me, it's not a problem and I've never had a problem OC'ing. Smoking is another thing.
It's become a ritual for me to walk around MCV smoking a cigarette just to aggravate the VCU Police.
They claim to own or control the sidewalks and in some instances, the streets.
We had a member who was a patient at MCV that dragged his IV Stand out on the sidewalk to smoke. The Cops told him he had yo go across the street but would arrest him for taking the stand there. The Chief claimed it wasn't true when I called him on it.
Legally, you're OK as long as you stay off of VCU Property but as a student, there is always the possibility that they could take disciplinary action and unless you have a pocket full of lawyers, you're in trouble.
There are students that do it. VCU has a small SCCC group and I expect they've mapped out free Richmond from VCUland.
There are or were VCU students that are members here. Hopefully one will shed some light on the subject.
