Groundhogs are woodchucks are Whistle Pigs. Honest. Groundhogs/Woodchucks stand up on their hind legs to keep an eye out for predators, and if they see one, the let out a whsitle, and tumble over backward into their holes. I worked at a Museum for many years, and we had groundhogs on exhibit. I also have a nice photo of one stretched out on the limb of a tree, with legs dnagling down. They aren't great climbers, but this was a tree in the exhibit that was only about six feet tall.I was a radio weatherman for 7 years and learned qhickly that the weather can be different three or four miles away.. be raining in one place, and dry as a bone for or five miles away. My best advice is, if you want to know what the weather is like, look out the window. I've heard weathermen forecasting a sunny day, when it was raining outside the building.
Woodchucks are probably better weathermen than weathermen are woodchucks.
