Instead of riding I took the bus home Friday, then got off the bus and picked up the boys at daycare. The trip home was by bike with the trail-a-bike and then the Burley trailer attached. Maybe I should get some "long load" signs for that configuration.
All was not perfect though when I realized I had forgotten to include their helmets. There we were, dad with a helmet and kids without on the ride home. Sorry kids, I'll do better next time.
