I-287's completion in the 1990s spurred this town's transformation from rural community to metropolitan suburb. The housing stock reflects the shift. Modest 1950s ranches share a zip code with 13,000-square-foot Hamptons-style shingle homes.
These days Franklin Lakes is known for some of the best fishing in New Jersey and some of the best catfights anywhere. Where else can you catch largemouth bass, black crappie and pickerel or bump into "The Real Housewives of New Jersey" for sport?
