Yeah - I don't know a thing about roans... My experience is with Arabs, who you can tell are going to grey because you see it on their face early on. Your roans don't start there. She may be like your other one, who looks completely different every year!
I took some other pictures this weekend at the arts festival. They turned out pretty good. There was some interesting stuff there. I took quite a few of the old buildings in the downtown area and the University campus. This is the town where I grew up. I'll post some of them later when the page changes. I don't want to put too many pics on one page.
