If you don't already have a bus pass can I suggest trying one out for a month? I just bought one March 1st and I have already used it way more than I expected to. I am almost giddy when I can hop on the back of the bus and don't have to wait in line at the front to stuff my change into that little money slot and ask for a transfer. I feel like I have just been accepted into this secret mass transit society, I just wish we all had a secret hand shake!
