Nothing much more to say 'bout that. I found that if I don't get curious about side streets or stop to talk to people the ride here and the ride home take about the same amount of time--22 minutes. That is riding mostly in the streets, but taking to sidewalks when the hills are long and the shoulder narrow.
The distance is just over 4 miles (6.7 km or so, I keep forgetting to check/reset the odometer).
My coworker Kendra rode yesterday and today. She is a bit more skittish about riding on the road than I am. For me it is just a return to my Kosin days, only the ride is about twice as long.
Today I passed a guy on a bike, and he followed me most of the way to work. That probably pushed me to go faster than if I had been on my own.
