A very cool company, Intrepid Travel. Not expensive either, and they go everywhere.
Mrs. BD wanted to schedule their trip to Jordan, but they are sold out for this fall. Friends told us that Petra was one of the most interesting places they had been to, and they have been everywhere. We rarely opt for organized tours, but for Jordan we thought it might be OK with us even though it's not exactly an exotic place. Mrs. BD wants to see all of the TE Lawrence places. 7 Pillars is a fine read.
Maybe I am a jaded traveller, but I have seen enough Greek, Roman, and Phoenician rockpiles to last a lifetime, and I've read it all, too. Jordan would be something different, with maybe a side trip to Israel.
