Riding the Lightrail train for the first time

Yesterday SPLโs cousin ACR (almost 8 now!?!?) came over to play with us after school. We decided to have an adventure and ride the local light rail train โ a 1st for both ACR and SPL. We took it about 5 stops and then came home. Not a long trip, but fun. And it was fun to watch ACR and SPL learn about the physics of riding a train ๐ โ
Kathy: ACR you should hold on.
ACR: Why? (and in mid-sentence the train pulled out of the station and he lurched backward :-). No big deal but he learned why he should hold on :-).
SPL just enjoyed watching all the people and seeing out the window.
