The Boston Lemur is a strange primate-like creature sighted around Boston that has baffled people for a while. In 2002, 20 miles north of Boston on a farm in Sherborn, a filmmaker named Andrew Mudge noticed a bizarre creature on a rainy day. He was visiting his parents' horse farm in a rural area, when he saw an odd animal hop out of a hole in an unused barn. It was the size of a small coyote and looked like a crossbreed of a lemur and a fox. The animal had short ears, a long face, and a faint striped pattern on its back. It also had a long hairless tail except for the ball of fur at the tip of it. Mudge thought it looked like a lemur, but he had spent his entire life in this area and never seen anything like it. He followed the thing into the woods. Mudge said it didn't try to escape from him, but didn't let him get too close either. It eventually got darker so Mudge headed back to the farmhouse. Mudge's father said he caught a short glimpse of it, too.
