I drove straight through to get home and made it just before 4am. Since we started cruising around the area at ~10am, that's about 18 hours of driving with only little stops in between.
Radar detector would never work there. Straights aren't long enough to detect the radar with distance to pull up. Either way, Dan and I got our certificates of awesomeness. Tim wasn't fast enough. Maybe next year, Tim. Honestly, we drove 85-90mph for about 600 miles on the way up there, pushed 9/10ths on the Dragon half a dozen times, did nearly triple digits on Cherohala, and burninated a narrow rally-like set of community mountain roads... I think a pink piece of paper and an on-your-way is doing really good.
If you look at Tim's first link, the last pic of my car, you can almost see light under the inside front tire. We were definitely putting some road behind us. I'm bummed that we never got a pic of Dan making front tire smoke (on the fender) or my brakes smoking.
