Last night I ordered Bicycling Magazine's New Cyclist Handbook from Amazon so that should be arriving in a few days.
I went to the North Hollywood YMCA at lunchtime. The pool is too warm, of course (86 degrees!), but it will do for what I have in mind. Looking at the people swimming while I was there, I don't have to be worried about being too slow (and I haven't swum laps in 25 years). That's good.
After work I went to Sport Chalet and bought my first pair of goggles since the seventies. They're Speedos and they're the only Speedos I'll be using for another forty pounds or so :-). I should weigh myself.
