Mark, don't get discouraged. When I had that tag, I only found sheep on one scouting trip during the summer. Then 2 days before the season they showed up right where they were suppose to be. Stay focused on learning the country - how the mountains tie together - where you can go safely, and where you can't. There aren't any secrets about sheep country in Colorado.
By the way, you spent your time on the wrong side of the peaks this last weekend near as I can tell from your pictures. Come in from the Buena side, up 4 mile creek, and check out the South side of West Buffalo and I think you will find what you are looking for.
Also, make sure to spend a weekend if you can out of Leadville checking out Empire Gulch, Iowa Gulch and that country.
Call me if you have questions or need any other tips - I'm happy to help.
