Montgomery County has two lines (both Red) whereas PG County has four (Orange, Blue and two Green). I don't think the "rich" ppl have a monopoly on Metro lines Granted, the lines in PG don't go outside the Beltway (except for Blue) whereas both of Montgomery County's lines go far outside the Beltway.

It just seems redundant to have Metro when MARC plies essentially the same route (95/295 corridor), doesn't it? I think another line through downtown should take priority, although the cost is astronomically more than extending Metro to the outer suburbs.

Lots of ideas, but no resources to execute... If DC were a human body, we'd be dead from asphyxiation by now.

HOT sounds promising. Congestion charging is the way to go, IMHO.
