&#62; 1) Stop subsidizing air &#38; road travel so much<p>Huh, I get that road travel is subsidized, but never heard about air. Do you know how that shakes out? Federal government or localities building airports, or providing some sort of free coordinating services, or some such? I had always just kinda assumed that airlines were renting or leasing airport space and covering most of the costs from it, but that was just me idly guessing.
