I was on Whitney early September 2015. We spent two nights on the mountain and I didn't see one ranger. Now, I'd like to go back this September, I'm checking for online permit openings daily, but still have nothing. If need be, I'll try the "daily" lottery when I get out there. If I don't get a permit, I'll respect the rules and will bypass doing the trail but I too wonder how many people are on the mountain with no permits.
If I ever had the nerve to call the visitor center Id ask why have a permit system in place, if no one is enforcing the rule.
I would guess 20% hike with no permit.
