These are very important things for someone like me. I am Hypoglycemic (discovered after the military) and get into real trouble without the correct foods on time.

As such, I keep a ready stash for three days in each vehicle and anywhere else I might be. (one MRE is enough for one day) Nuts, beef jerky,cliff bars, and other "healthy" snacks are a much better idea than say a candy bar for someone like me.

I know that the guiding principal is food won't be a problem in a short term survival situation, but short term for some may be measured in hours not days.

Edit:

Blast,

Someday if Houston is a destination and not a waypoint (or blur according to the hour), I am really going to have to get in on the classes.

Last trip to Houston was only a daytrip to kick a little corporate tail.
