Train Hard - Stay Humble
On a business trip in San Francisco, I learned the frustrations of living in a hotel for a week. I despise TV, so the majority of my nights were spent walking/training around Union Square. I couldn't find anything challenging enough in the area to really enjoy it, but still found it useful to force myself to explore beyond the depth that I usually would. I was extremely surprised that security had zero problem with me training in front of them every night.
This is the first video I've shot on my Canon 5D Mkii, with a 24-70 f2.8L. Self timer tripod shooting for parkour is definitely not ideal, but I definitely learned a bit doing it.
