Tool Bag / Go Bag

I was talking to a builder and soon to be flier the other day and suggested he keep a look out for a good tool bag to keep in the back of the plane when traveling.

I'm curious what you all have in your "Go Bag"?

Here is a partial list I sent him:
A small socket set
Gear wrenches in select sizes for AN3, 4, and 5 bolts
Safety wire & safety wire pliers
Flashlight
Screwdriver with replacement bits (Phillips, flat, and two sizes of Allan bits)
Extra gas cap and fuel sump
A small selections of miscellaneous fasteners
Electrical tape
Small battery tender / recharger
Small oil funnel
One quart of oil

extra tube for nose and main tires
extra spark plug (auto plugs)
small roll of fusion tape (rescue tape)
selection of tie wraps
multi-tool (survival type)
small survival kit (med kit, etc)
