When Dan Critchett, a real estate agent, meets a buyer at an open
house, a potential client he hopes to woo, he shakes the buyer’s hand and offers
two business cards. The first is fairly standard, a red rectangle that
identifies him as an agent with Stribling & Associates, who can help you buy or
sell a home. The second offers something else.

“Your introduction to Modern Hang Gliding,” it reads, next to a photograph of
two enthusiastic-looking people suspended high above the ground. “Sane
Affordable Fun.”

Sane? Perhaps. Memorable? Quite likely. One thing is for certain, however: Hang
gliding has nothing to do with real estate. And that, Mr. Critchett says, is
precisely the point.

“Buyer loyalty is one of the most difficult things to obtain,” said
Mr. Critchett, who is a certified hang gliding instructor. “You’ve got to have a
gimmick.”
