Needless to say, when you wake up and the temps are already well into the 80's, you do all your errands in the morning. I generally give myself a couple of those morning hours for biking and the rest for yard work and guzzling water. The system works, giving me the hotter afternoons to get housework done and maybe slip in a little book-reading time.
I guess that's the key to biking. You have to figure out what works for you. For me, weather dictates what I can do (and when). Otherwise, I'm pretty free to come and go as I like. For others, it might be dangerous intersections or hilly terrain or the fact that you have to actually look decent by the time you get to work. We all have limitations, but don't take yours for granted. Push the envelope a little. You'll never know what amazing things you can do until you try. So get out there and practice a little pedal power of your own.
See you on the road!
