+10 on the bug spray part.  Me and the boy scouted around up there about the middle of August.  The berries were green and small.  We stopped in near the Surpise Lakes area (but on the white people side) and found one (1) very old and dry pile of scat, but that was all.  I'm guessing we needed to get up into the wilderness area itself where there are fewer people...  The road that day was almost as busy as downtown Centralia...  (Ok for some of you, that isn't busy, but for me, being in Winlock, Centralia is a busy town!)
