2 gallon plastic can for lawnmower and 1 gallon plastic can of premix for string trimmer and blower are stored in the shed 100 ft from the house. Shed is always locked unless I'm doing something out there.
The 2 gallon can comes into the garage in the winter for snowblower season. It goes on a shelf 6 ft off the ground away from where my 2 year old and dog (and wife for that matter) can get into it.
For everyone saying that kids don't belong in a garage, let me ask you one question. What age did you start hanging out in the garage with your own dad, uncles, grandpas, neighbors, etc?
I know I was by 2 or 3 at the latest but I was always supervised. One grandpa had a small engine sales and service shop and restored John Deere 2 cylinder tractors and stationary engines on the side. The other was a truck and bus mechanic. There was always some sort of project going on at my parents house. I do the same thing with my 2 year old son. He's fascinated by tools, and toolboxes but we've taught him that he can't be in the garage alone and we're also teaching him what he can and can't do. He isn't allowed out with me if I'm using chemicals or power tools (besides being dangerous, the noise scares the hell out of him). Tuesday night he wanted to help me clean up after a remodeling project so as I put away tools, he used the shop vac on the floor. He was on a 30 minute mission to find every spec of sawdust. It helped me, kept him entertained, and you could tell how proud he was of himself for helping.
