Did you know that there are only 110,000 natural gas vehicles in use in the United States? That's according to an article in the WSJ, which goes on to note: "Experts say one of the reasons natural-gas vehicles haven't caught on is because the U.S. lacks a widespread network of refueling stations. Indeed, most of the natural-gas vehicles in use today are in government or corporate fleets that have centralized refueling stations."
