I hunted there last year, and I wish I could be more help for you. We never really got into good birds. The spring was really late out there last year, and birds were all herded up in cattle pastures and feed lots, and hadnt really moved up into the hills at all yet. We stayed mostly in the southern hills, down by custer and hot springs. There was definitely no shortage of birds, they were just all herded up.. This year should be much better for you.
Im not sure which maps you have, but the national geographic maps with the topo lines, all the public and private properties, and every little road and trail were a huge lifesaver for us..
Heres a couple pics for you to get you excited (if you arent already)..
