I'd suggest looking into the Meeker Colorado area. As for suggestions, I don't have a complete suggestion as to the DIY, we've been doing the DIY for over 20 years our family, but we live out here and its a little easier being close. For first time, I'd suggest a guide or a DIY Drop camp. Alot of outfitters will provide a drop camp and point you in the right direction. Then come pick you up in XX number of days.
