Courtesy of my 20 year old son, who apparently has absorbed some of my insanity:
Double Decker Bus Undercover Police vehicle. Theory goes: Who'd suspect it? Top deck could hold heavy weaponry, to take out fleeing vehicles, and the rest would carry loads of cops and listening gear.
I've been eyeballing the 1/24 Double Decker with envious eyes, and slowly, and surely, I'm drawing my plans to use it!
