As Bear Trap walks towards the wagon, your trained eyes pick up the tell-tale motion of a draw as Deke goes for the pistol at his belt.
ooc: Please roll initiative, evryone. Deke's got some skill with iron, and he will fire on 23.
In terms of positions, the Marshal is about ten feet from where the Mexican, Michael, and Deke are standing. Bear Trap is walking past Deke's left shoulder. The wagon is a good 50 feet further on. The two men near the wagon are still working at the rubble, and the man who was digging off to the side is now leaning on the handle of the shovel and watching events unfold.
D'Artois, Dakota, and Riley are 30 feet back from the Marshal, all with a clear view of the scene.
