Oh man, what a bummer. Did you give them a 21 gun salute.
I would suggest you show up w/case of beer, and a 5th of something for starters. By all means figure out some way to secure the game board (even if you have to screw it to the table). A 4X8 sheet of plywood, with a frame to keep the board from moving?
Sorry, I don’t keep mid game set-ups, I would suggest that you snap a few cell phone shots of games in progress in the future.
You can download some mid games from this site from ppl that play by forum w/battle maps. I’ve not done it (not sure what it takes), but here’s a link that gives you instructions etc… ppl are more then willing to walk you through it.

This next link (Play Board Games) is for games in progress, once you can download the maps you look at the set-ups in most of the games at different progressions. You can access the maps by looking for the the map down load through the players posts. This normally appears at the very bottom of a post, every 5-6 posts highlighted in smaller blue print (click on it). It will tell who’s playing, say what game (G40) and ends w/AAM.
