There is one thing I forgot to mention:
I must have counted AT LEAST 20 WAG BAGS along the trail.
Just past the last water crossing before Trail Camp, someone placed a green tent sleeve off-trail. You didn't have to look what was inside. You could smell it. Hideous.

I counted 4 on the SBs, 3 on the "Hypoxic Highway" between JMT and the summit.
