Lost in Camberville

Who would have guessed that both ends of the bike path in Somerville (the one that goes through Davis Square) lead to a Cedar St.? Not the same Cedar St., mind you. One of them is in North Cambridge, and the other is in Somerville. Despite being not very far from each other, the two streets are not connected or related in any way. So that's how I got horribly lost and confused yesterday evening and was more than an hour late to an appointment - my directions said to go to Davis and take the bike path to Cedar St., etc.
