Apparently it's illegal under New Zealand law for buses to have bike racks. I believe cycling advocates have prompted a reconsideration of the law, but nothing has actually happened yet. And bus companies in our town are private (with public subsidy), so presumably they won't install bike racks unless they want to or local ordinances require them to.

In short, I'm not holding my breath. But it certainly would be nice to skip the headwind on the 10-mile ride into town once in a while!
