I am new to Murfreesboro and was curious as to what the Discovery Center is. I didn't go in the Children's Museum (which looked very to be very popular), but I walked on the boardwalk exploring about 25 acres of serenity in the way of a marsh area. It was very quiet and the cypress trees were growing out of the water. There were ducks and ducklings, a variety of birds and turtles. Just a nice place to get away from the hustle and bustle and enjoy some nature. I recommend going to see it. There is no fee to take the walk, but the Children's museum has a very reasonable admission.
