First thing I thought about when I saw this thread's title: http://www.youtube.com/watch?v=RBVOYkhNb1o

I've got nice bikes with different characteristics, but I've had some magical rides - the most recent included sunrise highlighting the ground fog in an orchard, bridging almost effortlessly in the upper 20s to a breakaway, finding a bake sale at our rest stop, and maintaining a steady 21-22 mph into a 5-10 mph headwind when it came my turn to pull. I happened to be riding my carbon Look 585, but it would've been the same on my aluminum Allez or my steel Ironman.
