When I commuted from San Francisco to study at Stanford in the late 1980s, the San Francisco peninsula rail line @caltrain.com was a primary limiting factor on my education. It ran every two hours and stopped at 10 PM.

Took the high speed train from Taipei to Kaoshiung in just 90 minutes. Was unfortunately in the middle seat, but the upside: equal view outside both sides of the train. Also the ride is only 90 minutes!

When I take public transit in a new city, I like to write down my first impressions immediately. It’s important to remember what’s easy & hard so that we can channel that empathy to design more user-friendly transit.

Tomorrow's CA Task Force meeting is in Clovis (pop 125k), next to Fresno, at its Transit Center.
At that size, it should be somewhere you can get on transit (with planning), but the lack of connected transit in our state makes it impractical - for me it'd take 6hr 45 and involve 4 or 5 transfers.
