"A parking permit is required for hiker parking."
How does that work?
On reflection, its beginning to look like parking at Lone Pine, or even Mammoth or Lee Vining, would be preferable to parking at the Portal. Parking at the Portal requires a shuttle, exchange, taxi, Uber or hitch at some point. Easiest hitch I have ever seen is Portal to LP, and from there, trans is available all the way back to Yos, Reno, wherever. So I don't see any value to parking at the Portal, and no disadvantage in losing it for long term hike. For weekend or day hike, looks like it will still be available.
Soo what exactly is the issue?
