It is a rare occasion that I find myself driving on Glendora Mountain Road. Normally I am pushing pedals and burning calories not hydrocarbons to fuel my altitude change. I started driving up the mountain with a gas gauge hovering above the empty line. I thought I had enough to go the four miles up the road to the first saddle. I must admit the road feels different in a car. The lane feels narrower and the curvature of the pavement had a different dynamic over four wheels versus two. However on the way up the first time, the low fuel light came on. Damn. Oatmeal doesn't fuel a car. I panicked and headed down, on the way down the arrow pumps back up over the empty line and the fuel light goes off. Sigh. I could have made it to first saddle. I drove to a gas station put gas in and headed up a second time. And all the while I had a chance on Saturday to fill the tank, but didn't take it thinking I had enough. Lesson Learned. The Hard Way.
