faster, smoother, lighter... I use to throw my heavy mountain bike up on the rack with a fair amount of effort.. now when I lift my roadbike up I have to be careful not to overthrow the rack lol

Northern Kentucky is the easiest answer. My Avatar pic was taken from the Ohio side looking across to Kentucky. I like to go ride in Ohio as much as I like riding in KY. Lunkin Airport in ohio has a great biking loop.
