I am a little worried about my gas cans sprouting legs too. WIth gas at 3.50 a gallon, there's $20 in each can. Not only loosing the gas, but my favorite gas cans as well! I have a cable lock thru the handles, hooked to the trailer, but I rarely keep it locked. Suck a PITA when I need to add fuel to something and they are locked in. But I suppose the alternative, needing to put fuel in something and they are GONE is a lot worse! I'm going to force myself to keep them locked more now. Just too much money sitting there. I agree, people are a lot more likely to steal $20 in gas over a $500 backpack blower, just because they know what the gas is worth to them.
