early...you got it, it's called a pivot. On the second pic I was on top of a lookout at a dam in southern alberta. Lastly, I have never seen herds like I saw that day (mulies or wt's), well over 150 deer in 4 herds (as you can see). I have seen whitetails like this only once before (but only about 30 in a group) and they were feeding in a field close to city limits prior to any season. I see herds of 10-15 but never 75 in a group like the one field had.
