What was the last new thing you tried?

I bought a kerosene weed burner for my farm. (Propane ones are more common in the US and perhaps elsewhere, but not really here). I have a bit of fear of it, which isn't unreasonable for a big, pressurized tank of hydrocarbons near an open flame. I haven't gotten it to work right yet and I'm not sure why, so I'm a bit on the fence about it. We'll see how it works out in the long term. I am afraid to store it without the tank empty so it's sitting outside instead of in my shop.
