Look for the reflective material at a sign shop. Many carry the retro-reflective materials that appear a given color during the daylight and only reflect when hit with light at night. (like on LEO/EMS vehicles) Black is available. Does your ride have the Quick Detach wheels? If so, spare parts for that?? QD may only be a racing thing, I don't know.

Pepper spray for dogs is still a good idea. Lots easier to explain than a CCW discharge. (Or worse an accidental shooting due to shooting thru a dog.)



Edit: I just thought of this. What floor are you on at work? If not on the first floor, what plans do you have for evacuating from the building? I assume it does not include the elevator?
