As if the TNGA (my personal nemesis) wasn't long enough, someone decided to tack on another 300 miles to connect it to Pisgah. Yeah, that's 622 miles with 90,000 ft of climbing. That's like riding to the top of Mt. Everest from sea level 3.1 times if you're keeping score. Here's a link to the route.
I'd go ahead and ride it this month and post a trip report but I'm still recovering from this spinal surgery. Yeah... ;)
