Two Mile Run County Park is a nice place to visit in Franklin.
In the summer, you can go to the beach to swim, play miniature golf, walk on all of the trails, go fishing, play at the playground (children),or go to the pavillions for picnics, reunions, and other activities.
In the winter, you can go ice fishing or go sled riding on the hill. This is the best place that I have found in Franklin for sled riding, and just below the hill is a pavillion and fire pit, for those who wish to sit around the fire and talk or cook hotdogs.
Two Mile offers cabins for rent during all times in the year, as well. Staying at the cabins, so close to all of these other activities may be fun!
Tri-City Speedway is a racetrack near Franklin. During the summer, they hold the typical races, motorcycle shows, demolition derbies, monster truck shows, and various other events. On certain nights they may also have fireworks displays. They race every Sunday night in the summer. If you enjoy watching races, then Tri-City should be a fun experience for you.
