I was banned from his site years ago and haven't visited it since.
I had been to the Linden Museum in Stuttgart where they had an exhibition form Uzbekistan including a yurt described as a "men's recreational tent" - essentially where the men went of an evening to drink, smoke and whatever. I had interesting conversations with some of the exhibitors about their culture.
I suggest to Prof. Price that as a leading rug scholar and scientist, he should try an experiment i.e pin an old Turkmen chuval to the wall, get stoned, and look at it to see if it "waved".
I think he thought that was below his dignity.
