Cranbury and east windsor sound up your alley, plenty of farmland out there still, I grew up in the area and it’s great, my cousin actually owns the field of terror Halloween attraction and runs a full time farm in east windsor, but it’s developed enough that it doesn’t feel like the country, it’s about an hour to Philly and nyc, NJ transit Princeton is about 15 mins away. If all my work wasn’t in north jersey I’d head back in a heartbeat
