I'm pretty sure we are going to go through 20 packs of "C" batteries this month. We put our train around our tree for the first time since having kids. They both LOVE it! Gage just watches it go around and around and around. It never gets old for him! Maisey loves to use the remote to control it, to ring the bell, blow the whistle and play the music. She thinks she is so big when we let her do it!
