Affordable Bus Travel By Kristine Scott-The Fifty Co-Op, From: Maryland New to this forum!
Passing along information about two bus services I have used in the past.
Megabus
They have some very affordable fares.The earlier you plan, the better the price.

BOLT bus
I have used this service to travel from New York to the DC area. Although I have not been able to take advantage of one of their one dollar fares, I am glad to know that the option is there.
