RE: CO elk tag questions?
The first season definately has the least hunters, since it is a draw only season, but can only be gotten by the drawing. There could be some first season units that have left over tags (either sex), but won't be available until August.
The second season has the most nonresidents and thethird season has the most residents in an average year, at least that is what is reported. The later seasons are pretty much weather dependent: lots of snow means good harvest, but this year, the second season got the snow and better harvest, the later seasons were hot and dry. If you figure out how to predict that let me know!
As far as cow tags, there are some units that sell them over the counter, with a cap, but most units only have rifle cow tags through the drawing, so if you didn't put that as a second choice, you will have to wait until August and see if there are any leftovers.
