Gotten some good and thoughtful answers. . .

Except for the "No Chateau Bordeaux '65" at the restaurant sort of thing. .

If this forum was comedy, we are all dead.

But it does merit each of asking us what we are comfortable and least comfortable with. Subsequent thoughts ranging to "Would I ever be in that situation?" and, "is it worth my time?"

I love urban.

In order of how long I think I would survive:

Colorado:
---
Montane zone (8000-10,000 ft)
Foothills zone (6000-8000 ft)
Sub Alpine zone (10,000-11,500 ft)

Pacific northwest forests

Other forests

In a city

Coastal areas

Desert areas

At sea

Polar regions

Surface of the moon

Surface of the sun

The middle east

Surface of the moon? That would be a tough one. . REALLY need the special clothing for sure. . And, Geez, that would be a LONG way from home. . .
