I'll take you for a ride on my big orange tractor

Whenever the garage door is open and Grandpa and Grandma Hankins' house, Owen heads straight for Grandpa's lawn mower. He is all about getting up on the seat and reaching for the wheel. What is it about boys and their "tractors"? It is so interesting to me how different boys and girls are from the get-go...we don't even have to teach them to like trucks, cars, tractors, etc.
