...is a train.
We went to a petting farm this weekend, that had everything from chickens to camels. The camel was a nice camel that didn't bite or spit (it does, apparently, like to suck hair but we didn't get a demonstration of that). There was a family of wallabies, as well as a HUGE pig, and goats, sheep, and ponies.
I seemed to be more impressed by the petting farm than Tucker. He thought the animals were pretty scary, and that the wooden train they had set up in the yard was a much better way to spend our time. We spent about 15 minutes with the animals and 45 minutes with the train.
