Do they ever sell sleds in GA?Brilliant! Aart, but I'm hoping they're still selling sleds like that. I'd love to do that. I'll see what temp their pens get today.
I saw these earlier on FB I thought it was pretty brilliant too.

Maybe in the mountains.
Probably won't find one in July, I've had that thing for years.
I also use some other big flat pans....one is for putting under a washing machine, but it's really too big to handle easily...and some smaller ones(~16x16") I don't remember where I got them or what they are really for.
One of those mortar mixing pans might work good....or pan for under a water heater.
