We traveled to Leesburg, VA for Grapehounds-Virginia this year and the weather was great (except for a few passing afternoon showers).
We did a caravan up and stopped at one winery, Hartwood, with lunch. They had a great front porch that allowed us to let the dogs roam since it was completely enclosed. The greyhounds all laid down for a snooze, but even as an old man, Parker was still busy looking for crumbs. He found his way through many areas of the porch that had obviously not been traversed in a while.
