I've learned to ride in more variable weather. If I want to commute in spring and fall, I'm frequently leaving home with temperature in the 30s. I need clothing that can be adjusted as I ride or arm/leg armers that can be removed in a quick stop. I've also learned to ride in the occassional rain shower. I used to not bike to work if there was a 30% chance of afternoon rain, but I'm learning to deal with that and bike more often.
Oil is good, grease is better.
