The title may sound crazy and far fetched, but what do some of you think of a type of 'inter-planetary high way'...or just to the moon or Mars? The idea came from that 'elevator' that has been proposed to be built by some form of chemical compounds?? Forgot the name but it was something like that...i guess the 'high way' would take a long time to build, but would it work? Could it be built on that same chemical compound that was proposed for the elevator to the ISS?
It could be a type of train track, or some device where the space craft can be hooked onto and then propelled away....ok it sounds crazy enough

just a random thought.....
