Many folks know that monorail is prohibitively expensive because it's built on tracks up in the sky, not on the ground like light rail.
Light rail is the only choice being offered.
You kill light rail, you don't get monorail, you get nothing. Same deal for buses. Some oppose light rail because they want a better bus system first. Sorry, but killing rail doesn't give you an improved bus system, it gives you the same bus system you already dislike. Neither monorail nor a better bus system will magically appear if you vote down rail.
