It's a riot.
I live just North of Boulder. I am thinking of getting one, then going down to Pearl Street Mall with mine on. I'd get some good pictures, but I fear for my safety.
Another option is cruising past CU with it on. Priceless, but perhaps deadly.
You'll be fine. If memory serves, any conservative gal could kick the butt of the great unwashed that hangs out there. Especially in front of the courthouse. Just be careful that their B.O. doesn't knock you over first! :-)
