I live at 8,000 feet and they hang out up here all summer. There are a couple of ponds in the area.
No need for corn they just hang out. We may not see them for a week or so then they show up.
Last year during the rut a big bull was chasing a cow all over. I was standing outside and they ran between me and the house. Glad he was focused on her and didn't see me.
In Utah a tag is hard to come by, a very limited number are given out for each area. They did air lift some out of my county to Colorado last year. There were apparently too many but not enough to give more tags. I am sure there is some logic involved somewhere.
