I increaase the size of my map using photo shop. I forget the actual size, but it was about six feet long. I then divided up some of the land and sea units into smaller units. This will increase game play and the time. I did all this in photo shop. I then burnt it to CD and to it to Kinkos. They have a supper large color printer. I printed the whole thing and they laminated it to. Of course it cost me about $40 bucks, but it was worth it. I know have a real clean and clear color map with almost 1/2 more spaces and is 6 feet long by 4 feet (i think) and is laminated. I can use a dry erase pen on it if I want to and roll it up and take it anywhere. I also use a 6 large page claps (you can get them at any office supply store) and clap it to any table.
This is the only way to go!!!
You could make all kinds of maps.
