board (5 feet by 3 feet) with train tracks on it. We would then pull out
the train, plug in the regulator, and run that train around the tracks.
The other day we pulled out the very same train -- minus the wooden board --
and gave it a whirl. Isaac has gotten pretty good at regulating the speed
so that it doesn't whirl off the track. Daniel has a ways to go.
The event proved a third generation of fun.
