HopStop subway and train directions around major US cities
HopStop.com/pda will let you get directions around major cities using public transportation. You can visit the site above and easily enter directions, or you can send an SMS to HSTOP ( 47867 ) or call 1-888-2-hopstop ( 1-888-2467-7867 ) { I didn’t try calling, I don’t know why there is an extra digit in the phone number? }
It was totally painless to use the pda website from the phone.
