A guy who runs some encounters seasons started bringing a sheet of plexiglass to pop down on the maps. It solves the fold issue and lets you use dry/wet erase markers as needed.
Yet another example of an old idea coming back into vogue.
We used clear acrylic and markers for decades to put over maps, or to just draw encounters on.
When Tac-Tiles came out, we stopped doing it (but still used markers). But now that our DM is running Keep on the Borderland Encounters and hence has a ton of maps, it's probably a good idea to dust it off.
Thanks for the reminder.
