The next train wasn't til 5:37. I biked up to El Camino and waited for a 522 Rapid, which after 10 or so minutes, arrived. The rapid is definitely faster than the regular 22, but given that the 5:37 is an express, I probably should have just gotten out my current literary diversion and waited at the station.
I met up with my family in Menlo Park, where we went to dinner at Jason's Cafe, which has recently replaced Brix. Add this place to the list recommended transit-accessible eateries (from MP CalTrain, walk around the Foster's Freeze).
