I am currently running a d20 modern/future campaign, and I am doing it with no maps. I play via skype because all my old DnD buddies live in NY while I had to move to GA for work. I have only held about 4 sessions in which only one large battle has taken place. I had to describe in painstaking detail for me so the players had an idea on how things were laid out and their positions in reference to key pieces/ enemies.

I have just purchased Fantasy grounds with the d20 modern modules and would like to try avoiding spending to much more on trying to set up for this campaign, so Id prefer a free program if there is one. Thanks in advance for all the help.
