My boy "Blue" at Rock Creek Park outside of Erwin, TN. I'd forgotten just how much energy a four month old puppy has...Blue is keeping me moving. He's fairly content at home on the days we get out for a hike -- but that's going to be hard to keep up. Maybe I'll get a treadmill. ;) It was frigid today, but Rock Creek was a winter wonderland with snow clinging to the trees and rhododendron.
