I hiked up Mount Whitney in 2007 and needed a WAG bag to carry out my poop. I presume the requirement to use a WAG bag is still in place. So, for a SOBO JMT hiker, do I need to carry the WAG bag from my starting point or can I acquire one along the way (Muir Trail Ranch for instance)? Is WAG bag required anywhere else other than the Whitney Zone?
Thanks.
