Marc:

I needed a pair anyway. So I killed two birds with one stone.
I found what I was looking for at Dick's in NY in early Nov. Not being in a rush, I did not buy them then. Over the turkey holiday while we were in AZ, I found a coupon for Dick's. A quick visit to the Tucson Dick's reinforced regional differences. They didn't have the exact same model. While the NY boots focused on warmth and dryness, in AZ there were also snake proof! Not a feature I need for this trip.
I bought them in NY.
