Yellow jacket hill in Tahuya is a bitch in the rain. I got denied hard. Retreated before I broke something. Got half way up. Wasn't aired down so that might of been a factor (15psi should of been about 5psi), plus is was raining and muddy as hell. So basically slime rocks. But about half way up I dug a nice size 40" holes all the way across. Coming down was a piece of cake. Looks like more rocks got added or they moved all the ones that ended up at the bottom.
