"A blatant attempt to bank bbqs and grills."

At least non-propane models. More likely target is wood burning fireplaces. They've been after them for years around here in the Pacific Northwest.

I once had a manager that worked out there. He said he rented a house with some other guys (1970s), and the furnace burned sawdust.

It wasn't until he moved back East that he found out about the downside of sawdust from a Pac Northwest native. Fleas.

The manager said he always wondered about his ankle rash when he was out there.
