"The downhill from The Pinnacles to Thornton Gap is about as fun as riding gets -- fresh pavement, beautiful curves, 6% grades. Wheee!"
I rode from Panorama to Big Meadows (about 40 miles roundtrip) a couple of weeks ago. Stimulus funds have been used to repave the road and it is really nice! A few years ago the tunnel was a really rough ride.
I filled water bottles at Panorama (Thornton Gap) and there was no e coli issue. This was July 31st; things may have changed in the past few weeks?
