Yes, that's correct. Also, importantly, U.S. transit properties have been very aggressive in their switch to alternative fuels. The Los Angeles Metropolitan Transit Authority operates no diesel buses. They've done over a billion miles on natural gas. They retired their last diesel bus a year ago.
Nearer jurisdictions, in terms of climate maybe, are Boston, Washington, D.C., and a number of others that have adopted significant fleets of natural gas vehicles. At some of the annual transit conferences, they are sort of wagging their noses at some of the fleets that have stuck with diesel, due to the fact that they've been able to ride some pretty competitive natural gas fuelling prices, keep their transit fares low, and stay competitive.
