Always cross RR tracks at a right angle. That's one of the first rules you need to know when you start road riding.
I had a nice commute this morning, the first day this week when showers weren't threatening or already happening when I left for work. It was a little chillier than previous mornings (low 60s) but still warm enough for shorts and a short-sleeve jersey with no arm or leg warmers. The strong SW wind we have had all week finally died down, and that made my morning commute much easier as the route is predominantly south. I almost rode my single-speed, but was too lazy to switch my lights and other gear from the touring bike.
Bike to Work Week in my area is next week, and the "festivities" start this afternoon with free food and bike parade downtown. However, I'm heading out of town for Mother's Day weekend so will have to pass. They are having free breakfast for bike commuters one morning next week, so I might add another 10 miles to my commute that day just for the fun of it.
