Depends on what your definition of 'nice' entails... JC is a smaller town, that then has the pros/cons of such size. Relatively quiet, has some nice rolling topography, near the MO River, home of the state capitol, a nice shopping district, yet,,, you won't find much, compared to larger burgs such as Columbia [just ~35 minutes to the North on a very pleasant drive up US63], Springfield, etc. Just depends on what you are looking for.
