Nice route. Fell victim to sleepiness after stopping for a sit-down spaghetti and meatballs dinner in Solvang; I should have had a 5 Hour Energy. Instead, I had to slow way down, and then became cold and had to put on cold weather gear I ordinarily would not wear unless the temperature was in the 30's. I started to get desperate and thought about taking a dirt nap somewhere along Foxen Canyon, and instead decided to go "bat shit crazy", played some music and stomped on the peddles with a hoot-and-a-holler, singing out loud, and loudly, to the consternation of dogs in 2 counties. It worked, and I was able to regain a respectable pace. However, the damage was done as far as the clock was concerned, and I did not get to the overnight control in SLO until 3:23AM, and did not get to sleep until nearly 4:30AM. (Left the control by bike at 3:32, and arrived at my hotel parking lot at 3:40AM.) I was about 6 hours at the overnight before beginning to peddle again, with no more, and probably less than, 4 hours of sleep to show for it.
