For those wanting a bigger board to play on... I downloaded the board gif off of C_Sub's website. I went to staples and had it blown up to the largest size they offered. I also had it grafted to poster board and laminated there as well. It ended up costing me about $50 but now we have enough room to place our pieces. IMO it came out really nice. Worth it considering how much time will be spent playing this game.
Here is the link for the map:<edit> http://games.groups.yahoo.com/group/Caspian_Sub/

Respond back if someone knows a better way... I just needed something fast for Monday and didnt look forward to playing on the normal board.
