my experience is that if recumbent riders get any antagonism over their choice of ride, it's because they just got done telling a DF rider that they are doing it wrong. And then there are people like this, who just got done riding his recumbent 750 miles in 88 hours. It was a pleasure to meet him, he was smiling both times I saw him, even though the conditions were rainy and cold and the route was pretty brutal with over 60000 feet of climbing. Second time I saw him he had a DF rider drafting him up a mountain. He was one of 22 finishers out of 48 starters.
