We now have the ISBN for Public Transit!  The final proofs are on their way as I type this.  Once I make any final revisions, Public Transit will be available to purchase from the usual suspects (Amazon, Borders, Barnes & Noble, etc.).  Hopefully, this will be by mid-February.  We’ll keep ya posted :-)

UPDATE: For those interested, the ISBN will be (as in future tense, so don’t look now) 978-1-4303-1996-2.
