Maybe its worse with M.S streets since it only seems to show the
federal name. I've noticed that back home in Sacramento. It lists
streets as U.S. 123. I've lived in Sacramento for 20 years and never
knew those streets by that name. It would be nice if street signs
listed both names. I do have a map, its M.S. streets. Since I knew the
museum was at the airport I followed the sign that said "Airport
traffic". WOW, BIG MISTAKE. That is the 7 mile long, no exit, no U turn
road that takes you to the terminal.
I do have to say that once you figure out the Metro it does work
nicely. They run frequently and seem to run on time. It is more
complicated than other city trains I've taken but it works. You
actually seem to pay by the mile, so when you get on the train you look
up the station you will get off on and it gives you the price. Each
station to station is a different price. I still think the Paris Metro
is easier to understand though, they just use zones to distiguish
price.
