MCTS is clearly a public transit system. There may be other buses operated by non-public contractors to the city/county or buses operated by private companies. These certainly have the righteous power to permit/prohibit at will.Originally Posted by Wisc. Stats. Ann.
I recently toured national parks in a few of the states with more liberal gun laws than Wisconsin. It may be recalled that national parks have had to follow their state's gun laws. Also many national parks are removing private autos in favor of mass transportation buses - operated by private non-public contractors and franchisees. All that I noticed had no-guns "ghostbuster" signs.
