Z loved the various means of transport he experienced,some for the first time. The car ride to dayton airport. the people mover to our gate. the actual plane ride to atlanta, then another plane ride to denver. at denver,it is huge and to go from east to west terminals, you take a train. complete with train sounds piped thru a PA. Z knows lots of words and sounds to go with transportationso it was very fun watching him enjoying the rides and expressing himself. WOO WOOO....aaaall aboard!!!!
