Selkirk Society.

Having traveled on an unusual journey with R. Crusoe & Son, you have become a member of our Selkirk Society (named in honor of the intrepid gent whose adventures inspired Mr. Defoe to write his book). Less venerable than the Royal Geographic, perhaps, but with more practical benefits. We humbly and cheerfully offer the following (discounts apply to most journeys, but Private Jet and Special Interest Group tours are among those we_re sorry to exclude):

SEND-A-FRIEND DISCOUNT. Refer a traveler who's never taken a Crusoe trip, and receive a five percent discount on your next booking once your friend returns. You can accumulate as much as a 50 percent discount on any one trip. Just pass on your friends' names by calling 1-888-490-8045, faxing 1-312-980-8100, or emailing us at info@rcrusoe.com.

FREQUENT TRAVELER BONUS. If you take two Crusoe trips within 12 months, enjoy a five percent discount on the second trip.

GATHER-A-GROUP DISCOUNT. Put together a group of at least 10 people, and you can accompany them free as the 11th traveler. Gather eight or nine travelers, and you'll pay only 50 percent of the tour cost.

TOMORROW'S NEWS TODAY. Hear about new R. Crusoe journeys, and have the opportunity to make priority reservations. When Bhutan opened up to visitors, for instance, Crusoe had the information right away. For bi-monthly specials, register at www.rcrusoe.com/forms/keepme.asp.

MANAGING DIRECTOR'S JOURNEYS. Be among the first to hear about opportunities to travel in a small group with R. Crusoe's managing director, David Weber. These journeys are jam-packed with special features, and they fill up fast.
