Oh let me count the ways!!! Since Christmas, he has been playing with this little truck set A LOT! We would just get it picked up and he was over asking one of his sisters (or mom and dad) to get it out again. The truck (there are actually 2 trucks but he has misplaced one already) only takes 1 AA battery, but we have gone through at least 10 batteries. The funny thing is--the truck doesn't get much "track-time." He lets the truck go around the track once. Then he picks it up, plays with the wheels, turns it off and on, and then puts it back on the track. It is delightful to watch him play.
