My husband picks up our kids at least three days a week from daycare/school using a Chariot (I think they were bought out by Thule, sold at REI). First we had the single, then the double, now back to the single with the older one riding her own bike. Daycare is about 3 miles away, school about 3/4 mile. He thinks cars are more careful when they see the trailer (always with the orange flag flying) than when he is riding to them by himself. The kids love it and beg for it, even in bad weather. We like the idea of the steel frame trailer more than if you have a seat on your own bike. And the great thing is that now the older thinks biking is the only way to get around short distances, instead of a car.
