The good people of Free Spirit Siberian Rescue regularly put on dogsledding demonstrations. Check 'em out. I can't resist a dog photo.
Camera Nerdery: Yes, I've used Lightroom for evil: this photo has a sub-par background and marginal lighting, so I've band-aided these issues with a skosh of luminance tinkering, a smidgeon of highlight split-toning, and yes [gasp], even a jot of vignetting. ...maybe a couple other things too. I've used Lightroom to "instagram" a non-phone picture, but I swear--it's better this way. My confession aside, this was shot with an 85mm f/1.2 mounted on a 1Ds mk III. You were probably told it's impossible to shoot action with the 85L. It's not. Though it does require more anticipation.
