There was a site out on the interweb called MegaMoonLiner which had two US destroyers which could be downloaded for free. My son wants to build a ship and these are not so simple as to look like toys but not so difficult as to frustrate him. I failed to download them while I had the chance and now they are gone. They indicate they are offered out there somewhere but are not too specific as to where. Does anyone know were I could get them?
