Do you ride Amtrak with your bike already? Are you thinking of taking a trip with your bike? Considering a family vacation that would be easier if you could just ride the train with your bike? Then I encourage you to take the Amtrack Bicycle Survey. Now is the time to show Amtrak there is demand for better accomodations for bicycles on trains!
UPDATE: After reading this more closely, the survey appears to be focused solely on the Amtrak Capitol Limited route. Still, a good response on this route may well encourage them to put out surveys for other routes.
