My grandfather has a remote control monster truck and during our visit last weekend Austin was able to "drive" it.
It took a little while for him to get the hang of it, but once he did he couldn't get enough.
And, of course the tongue out as he carries the truck back to the straightest stretch of driveway. What is it about boys/men and their tongues hanging out when they are doing strenuous or skill driven tasks? I don't think I have ever seen a girl/woman with her tongue hanging out in a similar circumstance. I guess it is just one of those things that "makes you go, hmmmmm?"
