Picking up errant WAG bags is a noble thing to do, but let's not forget that it wouldn't be necessary if they stuck with the preferred alternative in the Environmental Assessment to replace the old toilets with new ones.
WAG bags left on the trail was a predicted impact described in detail in the EA. They also predicted more cat holes, side trails for people looking for privacy, and concerns for water contamination. They implemented this voluntary wag bag solution fully informed of what was going to happen.
Thanks again JAGCHiker for going the extra mile to pick up after others and for trying to recruit help in that effort. We need more people like you out there.
