It's BIKING? Yeah. That's easy for you FLATLANDERS. Try living in Hill Country!

My backyard:

I live across The Mighty Mississippi from Dubuque, IA. The Glaciers never touched us. We are still as God made us to begin with, which proves to me that God was NOT a biking enthusiast and this study is bogus. ;)

Those hills are God’s way of telling you that you need more exercise.................................

You call that a backyard? THIS is my backyard.

I live on the mountain side near the left side of the picture.
