Where can I get 30 gallon barrels?

I have a pile of wood waiting to be burned, but have yet to find a 30 gallon barrel (or two) to use for a tilted barrel style burn.
For strength/health reasons I cannot deal with a 55, it's just too big and heavy.
The place I thought would have them (as they have all kinds of things) do not.

What comes in that size barrel? Who might use them? I don't even know where to look for a used one.

Thank you!!
:D

They are hard to find, and tend to cost more than the 55 gallon ones.
I gave up on getting one and  I use 40 gallons water heater tanks instead.
I'm not sure if that will help you, the tank is still pretty  heavy, at least until it's cut down to size.

I've seen grease come in barrels about that size,

Echo what Jordan said. Check with a truck or tractor workshop, as they go through a lot more grease than your average auto mechanic.
