    "Other than events at the local farm there aren’t any. People live out here to enjoy the quiet views and find other things for entertainment. There are many great things to do around if you are willing to take a short drive. "

    "There’s no side walks for dogs to walk along. Also, the cars speed too fast along the route 57. And some areas off of the side roads. The side walks are only in the upscale area of the town and the rest of town is beaten up and needs repairs on houses. The house along rt57 in Beatyestown are not in best shapes and the river along the highways floods frequently. "
