I carry mine on the bike all the time. What surprised me is that I can legally park a bicycle in any on the road (not on private property) car parking spot. And my friends are surprised that a cop can check your brakes and give you a ticket etc.
(c) A bicycle may be parked in the roadway at any angle to the curb or edge of the roadway at any location where parking is allowed.
(d) A bicycle may be parked on the roadway abreast of another bicycle or bicycles near the side of the roadway at any location where parking is allowed.
