I love that statement ... "didn't bring the 400mm lens" ... so casual, so matter-of-fact, as if everyone has a 400mm lens, like, "I didn't bring my boots". So, you walked nine miles. That's about 15 kilometers, but I guess you walked it on the American side. Oh, wait, I'm sorry, you're right, it's miles, cuz I forgot that according to President Elect Donald Trump we are now the wonderful 51st state. Someone should inform all those waterfowl that they no longer need to worry about customs and security at the border. Wait, there's something not right here. Didn't we just spend, or promise to spend billions festooning the border with bureaucracy? That bureau crazy! Way too many desks to fill. Oh right, some of it will be in the form of drones, all under control of the head drone, Donald duck. Still, 9 miles, or almost 15 metric clicks, that's pretty good. It's like tackling Tommy Thompson Park in totality. Your back must be getting better and that's a good sign of great things to come in the New Year.
