that Kansas is so flat that there are spots on I-70 where you can see the curvature of the earth. Well I thought he was just blowing smoke until I rode east from Colorado across Kansas and discovered the following ...
1. as you leave Colorado and enter Kansas I do not believe there is a 'Welcome to Kansas' sign
2. western Kansas along I-70 is so flat that there are spots where you can actually see the curvature of the earth

3. Colorado east of Denver is pretty darn flat ... even before you get into Kansas
4. see #2
