There is one problem though, that creeps up. That is at GMU, the only visitor parking is in one of two parking decks. If they could consider a parking deck a building, then visitors won't be able to carry from their car to the "outside" according to the bugus anti gun rule.
If this concerns anyone, I would suggest parking off campus on the sholder of Roberts road across Braddock road from campus. You can get a map of what I am talking about by entering the search terms: "Braddock Rd andRoberts Rd Fairfax, VA 22032" into google maps. There is a nice graveled sholder there, and plenty of room to park, by the time 5:00 comes along.
