I don't have long but I will say it's a fantastic place to live and raise kids. Schools are amazing. BT has it's own K-8 school and then the kids go to Mountain Lakes High School (ranked 4 in NJ this year). Taxes are terrible like the rest of NJ.
Loads of things for the kids to do...the rec department is great....all the usual T-Ball, Soccer, Tennis etc. Lots of activities are either with the kids from ML or ML and Boonton. If your kids are younger (pre-school) there is an active Moms group that does stuff year round. DM me if you need more info.
