Best of luck with the unlimited hunt.
Which unit are you thinking of applying for and what is your strategy with scouting and hunting etc? I have done a bit of research on it and will certainly give it a crack shortly. Coming from Australia and doing it on my own i need to plan a hell of a lot, but certainly i would be looking at it as maybe a three year deal. First year you get a good feeling for what your in for, areas to hunt, how long you can go on your own in that terrain out of a pack before heading back to civilisation and refueling, maybe see a few sheep, and who knows the quota could be filled in 48 hours, or it could be a tough year and stay open. Weather and temperature will no doubt affect sheep movement and range and i reckon if you gave it 3 solid years, you would have to put yourself in a position to locate legal rams whilst the hunt is still open.
Keen to read everybodies thoughts on this, as i certainly spent plenty of time reading about the unlimited areas for sheep.
