Which Raritan? Somerset County, Hunterdon County? There are at least 2 Raritan's in NJ. edit, nevermind, I see you mentioned JnJ.

The area around Raritan is very suburban. You'd be doing an opposite commute of many but I guess for a more urban feel you'd want to head out toward Jersey City or Hoboken. That is more like 45 - 50 minutes away though.

Morristown might be worth looking at. That is 30 minutes away. Somerville is not very urban but it does have an excellent walkable downtown area. It borders on Raritan.

Or just embrace the next county over (Hunterdon) and go full on farmer.
