Nah, when that happens, you never think to be grateful for the constant tailwind. You just think, man, I'm fast.
I've done that; Suddenly, I'll have picked up 3-5 extra mph on a course I regularly do and I'll think, "Gee, I'm getting good at this!", and then when I turn around to come back the wind smacks me in the face and I realize I'm not actually getting good at it...
