With your results already up it really makes me wonde why it takes so long for Colorado to get theirs up.
Your question should be why does Colorado wait until March to start their application period? Every state is different. You can take Utah as an example. They haven't even set the tag quotas yet for any of the draws and that won't be done until May. So you could put in for a tag that will not even be offered that year. That happened to me one year.
There can be too much of a good thing with antler rattling.
I like to hit the horns together for a good 30- to 40-second rattling sequence and then hang them up and resist the urge to hit them again.
This works to the hunter's advantage, because if a buck has heard it, he may have been 300 or 400 yards away and he comes in and he's not exactly sure where it came from.
When finally is time to rattle again throw a slight change-up into the routine.
The second time, don't rattle as loud...
