With the recent events in Dallas, I have been thinking about a Tornado shelter. Live out of town have been looking at a prefab shelter for about $7,000; but found a used bulk propane tank (30,000 gal) for $1,200 that has been condemned. It has a very small amt of damage to one side, so it will not hold gas but, looks great for a shelter. Thinking about getting it and taking on a welding project. Wanna kill these ads? We can help!
