San Bernardino County yesterday gained the distinction of being the first county in the metro Los Angeles area to have every single transit provider available in Google Transit, with the addition of the Twentynine Palms-area Morongo Basin Transit Authority. (Los Angeles County's hodgepodge of municipal operators are still struggling with implementation, while in Orange County the Laguna Beach Transit System remains stubbornly un-Googled. All of San Diego County is available, but since they only have two operators that's kind of cheating. Ventura County is similarly Google-challenged.)
Riverside County also gained some operators in Google Transit yesterday- the Beaumont-operated routes of the Pass Transit system (2, 3, 4, 7, 8, 9 and 10) and the Palo Verde Valley Transit Authority in Blythe. Only one transit agency in the county remains un-Googled, but it's a major one: Sunline Transit in the greater Palm Springs area. Their web site lists Google Transit as "coming soon", but it has for several months.
