You can do a lot of stuff at home. It isn't wilderness (usually), but it's close and exposed to the weather. And if it's hunker-down time after a power outage, a tree comes down on the house, a earthquake collapses your home, you still might have to live in your back yard.

You can practice fire-building in rain or with one hand.

Try some nonfancy outdoor cooking (without the propane or briquets). Got edible plants like cattails nearby? Why not collect some and cook them?

Had to take a tree down or clean up some large fallen limbs that fell in the last storm? Use them to build a shelter. Even if you don't spend the night in it, you can see how it holds up in wind, how much rain got inside.

How many ways can you collect water? Can you create an above-ground solar still with the stuff you carry in your vehicle?
