Playing around on this rainy, cold, windy-ass day: Daecon driving Union Pacific 4014, otherwise known as "Big Boy", the largest steam locomotive ever built (in keeping with the "big" theme, the original drawing is 10,000 pixels wide!):
I should also point out that this is drawn to scale. See that tiny little Daecon way back in the cab of the locomotive? That shows how big this phucker is.
