Do You Have a Survival Go-Bag?

Oh! That kind. I was gonna say a few good known working spare parts in the trunk are a carry along item. Ballast resister, Alt. starter relay.....

During winter months, it's a spare blanket and jacket/sweat shirt. An extra bag of this when I travel with the kids. Getting stuck in sub 30* days is a bad thing.
Not so much food or water. This island is fairly populated, so there is no worry like the need for water in the desert.
