we live on 20 acres 10 min. out of town.

We have a 250 gal. gasoline tank for tractors, etc. We refill at 1/2 empty, so there's usually 100 to 150 gal. in reserve. It's not really any cheaper, but there is a "rolling reserve" of fuel available.

As long as it is smokless, and isn't sealed up in a really tight container, I suspect that all it would do is go whoof, and make the fire burn a little better. Black powder, on the other hand, could go boom...

I'm reading everyone's advice -- but the implication is storing even a little bit of gas is bad? I have (3) 5 gallon metal CARB-compliant jerricans in my garage, for the portable generator. They have rubber gaskets around the (seeming) tight screw-on lids. And of course I have electric in the garage -- lights, garage door opener, wall sockets. How much risk am I exposing myself and my family to? Is there a safe way to store small amounts of gasoline for this purpose?
