Trains, Planes, and Automobiles

1. Charles has an obsession with trains and he is addicted to watching this 9 minute train clip. Every time we go near the computer he says trains. Meaning I want to watch the train clip. When we go home for Christmas we are checking out the Misty Mountain Model Railroad Museum in Blairsville, GA.

2. Charles is also into trucks and cars. When we drive down the road he has to tell us if it is a truck or car. If it is an 18 wheeler he says big truck. Conversation in the car: " truck, bye bye truck, where did the truck go, I don't see it, I don't know." This is repeated like a broken record, but it is very cute when he gets all excited.
~I really don't have much to say on planes other than he can spot them at various times. He has 3 toy helicopters.
~Are these obsessions of boys from a young age or what?
