I was sitting in my blind this morning when something ran about 15 feet in front of it. It was about 3 or 4 inches tall, had a body about 10 or 12 inches long with a bushy tail about as long as it's body. It was a dark brown color. Does that sound like it would have been a weasel?
As far as changing color you commentted about the tail being long then "if" it were a weasel it would be a long tail (aka New York) weasel and most of them would not change color in the winter. A short tail, smaller species than the long tail, has a much higher chance of being white. I've never seen a brown short tail in winter.
