Here's what Harley-Davidson's Web site says:
Harley-Davidson needs your help. We are gathering as much information as we can about the "Mother of All Roads," Route 66. If you have traveled any or all of the segments of Route 66 listed below, please take a moment to complete a survey about the conditions, sights, and amenities you encountered on your bike. Please complete a survey for as many of the road segments you have experienced. The survey questions are multiple choice and should not take more than a few minutes. Please do not take a survey if you have never ridden on the road.
Click on a Route 66 segment you have traveled to launch the survey. Once you complete a survey, you will be brought back to this page so you can take surveys for other segments as well. Thank you for your participation.
