It had rained the day before and the accuracy pea pit -used- to be right next to the swoop pond. I guess the rain had made the area near the peas pretty muddy and I was too stupid to actually walk out to the landing area before jumping to check it out.
I stomped the center of the peas and was running out the landing when I ran out of dry footing and slid on my butt for another 10 meters.
In case you ever run into a similar situation, just let everything completely dry, then attempt to flake off as much as you can with your hands. After that, you can try brushing off the rest with something that has fairly soft bristles. This worked pretty well for my rig, but I'll probably get it washed on my next reserve repack. As for my jumpsuit, I just tossed that into the washing machine (after the brushing step) and it cleaned up like nothing had ever happened.
