Here in Detroit, south of 8 Mile, we fly a tough breed on carrier, off a concrete (not plywood) deck.  While this saves a lot setup effort, it scuffs up the toys pretty bad.  So while they're out flying F2D in the snow in The Ukraine, I'm in the warmth of my basement patching up the the last few year's damage.
