Some of you may know, I claim to be an "old school" guy. I have used everything from graph paper to laminated dress cutting boards, to battlemats. I've started to get these maps (both Packs and Flip) and I can't believe it took me this long to use them! Very versatile (with a little imagination) and endlessly repeatable. We've had several waterfront battles in our Kingmaker campaign, and the players love them!
