Great shots, my man. Reminds me of back before I had kids, I would go on walks all night, and keep going the next day. So many interesting things to see and explore. Even now, 20 years on, I still feel the same way.
I still go on walks at night, but they usually involve a stop somewhere to grab a beer, then going home because the kids will be up early. Ah life.
Hope you get over your jetlag soon. But enjoy the early morning walks as long as they last.
