Barnstorming on an Invisible Segway

I feel about the place name "Riverside" something of what you feel about the surname "Kushner." Why on earth am I going to Boston College when there's a trolley leaving for RIVERSIDE in only 6 minutes? (I grew up in a Car Empire, and the distinctions between subways, trains, buses, and trolleys are not entirely clear to me. But if it isn't underground, it must not be a subway, and if it goes to the Land of Make-Believe it must be a trolley.)
