I lived in the Denver metro area at the time.
I knew one Saluki breeder just north of Colorado Springs. I would go on open field coursing and lure coursing trips with them in parts of Colorado and Wyoming.
I saw Salukis from all over that general area. Not a lot of them I suppose, but the circles I ran in meant I saw them on a regular basis.
I considered raising one myself, but once I had three borzois I had reached my limit. I also like grey hounds and afghans, though the latter don't suit my personality very well.
