After Isaiah worked up the courage to climb onto the back hoe, his first remark was "Oh!!! It has no keys!!" This was both an exclamation of relief ("phew!! This thing won't move and make noise!") and disappointment (because, of course, what little boy doesn't dream of driving a tractor?). Joshua was fearless, probably a little too fearless, and climbed up like a little monkey. He was glad to look over the edge and touch the big tires.
As a side note, I'm not sure why the boys both ended up wearing orange shirts... but fitting for my little construction workers, wouldn't you say?
