PERIMETER POSSE Patrolling the perimeter of George Bush Intercontinental Airport is fun with a sense of purpose, say (from left) Susan Reichenthal, Eve Lapin, and Barbara Levy, who love being in the Airport Rangers. The three also do pack trips in the summer, going off-grid on camping and riding adventures. (Photo: hartphoto.com)

WOMEN IN THE WILD Everything’s better off-grid to these women who prefer a rugged experience, camping and riding through a myriad of points on the globe, like here in the Canadian Rockies. Pictured, from left, are Barbara, Susan, and Eve.

Two trips to Iceland found them on a different kind of ride with the country’s purebred horse known for the tölt, its smooth gait uncommon to horses here.

Barbara, Eve, and Susan ride even the far reaches of the airport’s perimeters, where law enforcement sometimes trains.

The Three Amigos, as they call themselves, pause on their horses during the Rockies trip.

A pack trip to Utah was one of many they’ve embarked upon.

A FAMILY AFFAIR "Ellen is quite the social butterfly," says her sister-in-law, Susan Reichenthal. "You have to run to keep up with her." From left, Max Reichenthal, Ellen's brother, Ellen and Susan. (Photo: lawellphoto.com)
