    "The huge amount of children. The fact that old town does lots of community events. Lots of dog owners and active people. I can walk to 3 different parks from my home- one of which is on the river and has a fenced dog park. It’s a great spot. Centennial trail is one of my favorites to take down to the water front park and back with my doggos. "

    "The Farmers Market every Saturday from 10-2pm is so fun and a great way to support local businesses. Arlington Hardware in old town is the one stop shop for everything you need. The Co-Op Supply is pet friendly and has everything you need for your pets or live stock. Aside from that, if your a social butterfly like myself, the White Horse Salon in town is a blast!! I love to take my dogs here and play pool with friends. The best thing about this town is the sense of community. I know the owners to almost every business and regularly make new friends who are also local or new to the area. There is nothing like running into great people you know everywhere you go. I love it.

    "People are always out walking their dogs, however the yards in this area tend to get small so if you have a bigger dog find a nearby park or runner. The neighbors don’t like visits from the neighboring dogs if they decide to explore."
