Does anybody hunt GMU 388? This is my first time hunting in this area.

I have only been hunting a couple times and this is my first time hunting into GMU 388. My brother and I are going about 11 miles west of HW 97 into Satus Pass in between Toppenish and Goldendale. Can anybody give me good information and tips for hunting mule deer in this GMU? If you have hunted in this area, any luck? I am a beginner and the more information the better  Thank you!!!
