The wsgi code for the dynamic parts of this website isn't fully open source because it has some exceptions for things like people who've told me they don't want their comments pulled in from external services. When I wrote my lightweight bus map it was all mixed in with the rest of this code. I've separated it out and open sourced it: github.com/jeffkaufman/nextbus.

(Prompted by meeting a Nextbus employee at a contra dance and wanting to show them how it worked.)
