Depends on where you are. For instance... here in SE NB Canada, you ain't gonna get no ash of size.

A mix of birch (20% max), maple, beech, oak,

If it's just for company, hot and short fires are best.

As for "dry", well, yes. But many peeps dunno how to tell. Look at the wood before you agree. At the ends, there should be open "slpits" radiating from the centre.

And, you can buy "wet" wood cheap this year or early in the spring and pile it correctly... three to four months of summer drying is fine.
