I started my 12 year daughter applying this year. If she stays healthy and still has the desire, she should be able to hunt them in the next 20 years or so.
I have a friend who drew both goat and sheep this year in Colorado and it was his first year in the draw lottery. In Colorado you have have 3 preference points to get into the lottery for rams, goat and moose.
Hinge-cutting serves several purposes in regard to improving both whitetail habitat and your hunting experience. There are two main types of hinge cuts including a cut for screening and funnels and a cut for bedding. Hinge cuts for screening and funnels should be done somewhere between the knee and waist to block a deer's vision as well as block a travel path. Hinge cuts for bedding should be done around chest high so that there is room for a deer to bed underneath.
