Interesting. The next time I do Mt. Whitney I am going to refuse a WAG bag and see what the response is. My guess is I will be told I cannot go up the trail without one.

Let's see if I got this right, you have a trail that above 10,800' level is most rock and you cannot bury waste all that swell, you have upwards to 200 people a day traveling this area during the quota season and you have a voluntary program for human waste disposal. It seem to me this is a recipe for disaster...but that's just me.
