For those of you that archery hunt the opener of elk season ( I will be going to Colorado this up comming fall) so last week in August/First few days of September time frame, how much do you call if any? Is it just too early and you risk blowing the elk out of your area, or do you do some soft cow calls? I am planning to hunt near wallows and water sources as much as possible, especially if the temp is high, but not sure on how much, if any, to call?
