Thinking about this more and reading your comments, it occurs to me that it would be interesting to have CYCLISTS rate their state, say on a scale of 1 to 10, on biking quality factors:

1. Road quality (paving, cleanliness/debris, shoulder width)
2. Driver behavior & education re: cycling
3. Cycling amenities (bike lanes, stoplights that recognize cyclists, etc.)
4. Quality of bike paths (bathroom/water stops at regular intervals, quality of paving, width, debris, maintenance)
5. What else? What other factors contribute to your thinking of a ride as good rather than bad?

Factoring that in with what the LAB people looked at might give a more accurate overall bike friendliness rating. Then again, all states can't be in the bottom five, even though most of us probably feel our state belongs there!
