The Rock:
I don't have other pictures. I never manage to bring a camera to my games.
The rules that were used were my own This is Not a Test, which were being playtested. The game featured settlers and paid mercenaries escorting a water caravan across an old highway system. The crux of the game was the caravan was a decoy, the lead truck had a hidden heavy machine gun, in order to claim bounties on a pair of wanted raiders. The trucks could move 6" or 9" if going all out, though the latter was not without risks. I had some charts to determine fire effects when they are attacked.
The roads are simple roof shingles with cracked carved in.
Hope that helps.
