I'm gonna take a look at some other projects and see what we borrow.

For starters:

• https://github.com/codeforamerica/adopt-a-hydrant
• https://github.com/tiffani/transit-mix

Found a better copy of Transitmix at https://github.com/boonrs/transitmix

Got started with the Mapbox guides. Once I get through them I'll start pulling out the reusable bits from Transitmix.
