Talking to my wife she wanted to know if there are showers near by>
I believe there is one available for a few bucks at the Portal Store. I've heard it's not the cleanest, but that's to be expected with the throngs of JMT hikers emerging from the trail and rinsing off their weeks of dirt.
A better option might be the hostel in Lone Pine - also owned by Doug who owns the Portal Store. I think it's maybe $5 for a shower there.
