Who on God's green earth is still using WET-ERASE CHESSEX MAPS?!? ONE USE OF THE COLOR RED AND THE VINYL IS F*ED!!!
Go to Home Depot, drop $80 on a clear plexiglass acrylic sheet you can then lay ON TOP of your Chessex gridded map... and then you can use Dry-Erase markers OF ALL THE COLORS you could possibly want! And clean-up doesn't involve a water sprayer and an entire roll of paper towels!!! For all that is Holy...
-- now awaiting the Gen Alpha gamer to show up and tell us both that flat-screen tvs are now so cheap we should both get with the times and lay the screen flat on the table in order to plug our laptops into it and thus be able to use actual pre-rendered artistic maps on-screen rather than hand-draw everything like the Gen Xers we are.
