I did my first split commute ever Friday bike to work, light rail to the airport for a flight. Fly back, light rail and bus home.

Monday drove to BART station, train to work then rode back to BART.

OK, I did put the bike on the car for the 2 miles home but it's still dark and a sketchy ride at night.

It worked out well, very fast, convenient and saved alllllll the cost of parking at the airport.
