I have a few tips for bike commuting in the heat:
- Bring lots of water (yeah, everybody knows that, but it's worth repeating).
- Take off your helmet the moment you stop riding, and you'll radiate a lot of heat out your head.
- Go to work early (not that I'm taking this advice).
- Ride just fast enough to get a breeze, but no faster.
Summer is a good time of year for transit adventures. Kids are out of school, and if you take a day off of work, you can go places with them during the week when everything's running. Late sunsets help too.
Last week I took my daughter to Great America via CalTrain and VTA light rail. This works splendidly, but be advised to bring extra clothes--you will want to go to the water park, and a long walk and trolley ride in wet clothes is not so much fun.
Plenty of other outings will suggest themselves. This morning I saw a guy on the train with a fishing pole. Now it turned out he was meeting a buddy at SJ Diridon and they were going to drive to a lake, but there are actually in plenty of transit-accessible places to fish around here, especially on the bay. Just bear in mind that your fellow passengers will appreciate it if you make sure to have a fairly secure container for carrying your catch home.
