For anybody out there who wants to do more with this data than I do, here are spreadsheets of Bikeshare membership by zip code and trip origination and termination by station through Sunday, April 9th. The District Department of Transportation, apparently, is planning on making all of this public soon anyway—so it’s really just a sneek peek.
Also! I requested the contract between Alta Bikeshare and DDOT, but they blacked out the parts most of interest to me—the price schedule. If for any reason you were curious about the fine print, have at it.
