I've lived in Hunterdon for 29 years and raised two kids here. My kids went to Clinton Town School (Small K-8), a quaint town with a real main street. They go to the North-Hunterdon Voorhees high school district. Clinton Township has a larger area, more students, and several schools but is also N Hunterdon/Voorhees.
The Flemington area might be an easier commute for your Husband. The kids go to Hunterdon Central, a much larger high school. Flemington town is small but surrounded by a much larger Raritan Township. A bit busier than the Clinton Area. There are other towns in-between as well. The traffic between Clinton and Flemington can take up to 25 mins, which might be part of your husband's commute.
Great place to live, we love it.
