I went on a virtual trip here yesterday. The guide is very good and we went on a camel. He has a strong accent and I didn't catch all he said. I did however, wonder at them. Somebody said they are very small and hot and cramped inside. How did they do it ? Nobody seems to know, but at the end of the day, from this peasant, they looked like a pile of stones, in a dusty, dry, hot and arrid landscape. Glad I didn't go for real. Mrs Bouquet. Hope this doesn't offend anybody, its just my opinion.
