I was able to bike to work just a single day of "Bike to Work" week earlier this month -- and biking in urban Boston is about as different as biking in Laos as you can get. Of course the roads are in much better shape. And of course there are more cars.
Here's what surprised me though. Through our entire 800 km in Vietnam and Laos, I never saw another recreational cyclist. I saw entire families on motorbikes (sometimes with a refrigerator or some other unlikely luggage). I saw small children on beat up single speed bikes. But I never saw another western cyclist (except the fellow riders and guides on our trip).
Boston, on the other hand, is full of recreational cyclists. Many ride bikes fancier and more expensive than mine, and a large portion of them, though not all, wear helmets.
But here's what they don't do. They don't obey "one way" signs. They don't slow down for stop signs. They don't push to the right if they are going slowly, and they don't call out "on your left" when they are speeding ahead.
I miss the car-free miles on the roads in Laos. However, I am surprised to also miss the lack of fellow cyclists now that I'm back in the states.
The highlight of my ride home was a stop in Fresh Pond where a red-tailed hawk family has made a nest on a fascade of an office building. Here's a
link to a video from the Boston Globe. There is frequently a carnival around the office building, with a gaggle of onlookers, some with cameras that have lenses longer than my forearm. Even without binoculars you can see the parents and at least one of the chicks. This is a sight,of course, that you would never see in Laos!
