Although it is a bit hard to see at this distance, YES, those are cows crossing the road ahead. And a few over to the right are strolling around also. This was taken on the bike path - or should I now call it the Cow Path? - that is part of Harrison Green Way.
I'm a transplanted New Yorker who loves the Tucson climate. On New Year's Day I have a bit of fun calling my (snowbound) east coast friends to announce that I'm drinking coffee while sitting on my patio. (:
