Back on the bike after business travel kept me in a car Monday and Tuesday. One of these days I may take the bike to Tijuana. Rail and trolley to San Ysidro, bike eight miles to Otay, lock it at a pay lot in view of the attendant that is starting to recognize me. (Next to the half dozen or so Wally's that are left there unlocked). Then walk over "la linea" and grab a cab to the plant.
If I get really brave I will take the bike down, but that will take a lot more scouting.
