The ability to fly a gyrocopter and lob Molotov cocktails.
The ability to fly an airplane and make Molotov cocktails.
Not to mention:
I can hold my own with a rifle. Not "gnat's eye at 1,000 yards", but well enough to bring home venison.
I can fix things.
I've done a bit of leather work. Not Don Hume quality, but practical.
My deep and intimate knowledge of pop culture.
Oh, and the last of the V8 Interceptors.
Yes, They laughed at us and our carburetors.
My charming and clever wit
Yer screwed.
I'm pretty handy with my hands and anything mechanical. I have a decent green thumb. I can hunt/fish and cook what I kill/catch. I have limited knowledge of edible/medicinal plants (more than most city-dwellers, but less than a true "country boy"). Unlike most people my age, I actually listened when my grandparents told he how they did things in the good/bad ol' days.
I can set up WANs, LANs, and various types of systems, if that's considered useful in the post apocolypical age....
