It's funny, really, coming across this just now. I'm currently living in Saskatchewan, right in the middle of the southern part of this Canadian province, and I've done some freehiking this year. Among other things, I came across a hunter's "tree blind"--basically, a ladder to a perch in the tree, for those wanting to shoot a deer.
I couldn't resist snapping a quick photo of me on the ladder in the altogether -- but now I'm wondering... Was I captured by another camera?
