Ace,
First, welcome to NJ.
The Clinton/Annandale area is pretty much what you see so far. Nice neighborhoods, decent schools, fairly suburban. And you are right, that commute is going to be a tough one. I think most of the online mapping sites will say that it's about 30 -45 minutes each way, but count on it being almost double if you travel anywhere near the rush hours. There are also towns a little further east that will make the commute a little easier, and are really nice as well, with all those same features, and some would say better in certain instances. Towns like Readington there in Hunterdon county, and Bridgewater just next door in Somerset County. (A little bit of self promotion follows as I am in fact a real estate agent in the area. You can go to my web site,
billkeegan.com - HOME, to get a link to many of these towns web sites and some of the resources & recreations available within them. THe site is currently being reworked, so it's not as polished as I like it to be, but much of the info is there and accessable.) As for stuff for your wife & kids to do, don't fret. These towns are suburban, not really rural. They've got all the social & recreational opportunities you would expect in any suburban area. Most towns have organized sports activities for the kids, some within the schools, and others through the town, seperate from the schools. Where you concerned about any activity or group in particular?
