I'm gonna try and turn my Rocket into a velomobile.  Starting to collect stuff to make it.  Hope to do something similar to what Lightfoot Cycles is showing on their website. http://www.lightfootcycles.com/viper.htm  I don't want to use all corplast though.  I'm hoping to be able to use some poly bags I've collected here at work.  They would save a lot of weight and are pretty much waterproof.  Input or other ideas welcome.  DJ
