Brandi - You are a good soul. Try not to worry about people who aren't considerate enough to acknowledge you. I have that happen to me at least once during my daily ride (and I'm dressed in "roadie" gear, riding a road bike, and usually going at a good clip). I have learned just to ignore it and not take it personally. I grew up in Pittsburgh where saying "hi yinz" to everyone was just what folks did--a very friendly city. Even though I now live in the "snobby inside the beltway suburbs of DC," I will always remain a Pittsburgh girl who will keep saying hi, regardless. Keep smiling and enjoying your ride.
