San Bernardino County, despite being a bit larger than Riverside, long ago became the first Inland Empire county to be completely covered by Google Transit. At the time, Sunline Transit Agency, the major transit provider in the Coachella Valley, was the only agency in Riverside County not to be covered by the transit trip planner. At the time, the agency's web site listed Google Transit as "coming soon," and had for several months. It's now been several years that that tantalizing graphic has sat upon Sunline's web site, and we still don't have Google Transit data for the agency. This is despite the fact that they have a Google Maps-based bus tracker, and have thus geo-coded every stop in the system.
Sunline, release your schedule data and join Google Transit already!
