Subject: Oman -- anyone been there?

We met a Swedish ornithologist/naturalist on a Lindblad Special Expeditions cruise last year who also acts as a guide in Oman; he was singing its praises as a wonderful place to visit and explore. Have any of you been there? I notice now, in travel magazines, an ad now and then for trips to Oman. What is it like? Cheers, Bill in Baltimore
