Mid to late September in my area of Clearfield County. Usually around the 14th if you were looking for something more exact haha. The elk here are starting to rub like crazy though. Gets your heart beating until you realize the rub goes 5 feet up a tree! Shouldn't be long now though.
One farm we hunt runs early. Every year, third week of August we get several buck rubbed clean. Last year first picture was the 21st. Not first year either. 2-3 year olds
Mountain deer just a few miles away hold for upwards of another month!
