Fundamental Ultraruning Skills: The poo in the woods

My good friends over at Ted's Google Group started a thread on paleo wiping.  This reminded me of several questions I've received over the years regarding the delicate issue of pooping during ultras. 

I am always a little surprised this question does not come up more often.  Here's the situation- you're thirty miles into a 50 mile run.  You're surrounded by nothing but untamed wilderness.  You have to drop a #2.  Since there are no porta-potties for another 20 miles, you are left with no choice but to drop drawers and let loose. 

I always assume everyone has the benefit of being raised in the sticks.  I sometimes forget my suburbanite friends have probably never had the opportunity to hone their wilderness bowel movement skills.  I am also somewhat surprised at the amount of anxiety some people feel at the thought of dropping a deuce outside the friendly confines of the plastic vertical coffins neatly lined up at the start line of races. 

My first bit of advice- practice.  Don't wait until race day to attempt a torpedo launch in the woods.  Next time you're out on the trails, find a secluded spot and give it a go.

So how do you actually go about jettisoning some excess weigh?  Instead of explaining the process in detail, I'll refer you to this video posted in the Google Group:

Here are some additional pointers not covered in the video:

• When actually squatting, it can be beneficial to hold your cheeks apart.  Sadly, I have to credit Mtv's The Real World for this tip.
• Keeping a small piece of biodegradable toilet paper in your pocket can help with the final cleanup procedure.
• When choosing a location to squat, most people simply wander a fair distance from the trail.  Make sure you don't inadvertently walk too close to a different trail or road.
• Know what the local poisonous plants... don't squat in them.
• Avoid plants with thorns, too.
• Same deal with bees.

Experienced wilderness dumpers... have any additional tips to add?
