That doesn't always work out though - I was evacuated due to a wildfire a couple of years ago and in the rush to get out (flames were literally right across the street) I completely forgot any medications I was on - that's not something you can easily get at Walmart.

Ever since then I've had a go bag packed and ready near the door, with a week's supply of pretty much anything I can think of that I'll need.

The joys of living in the dry southwest.
