Whenever I get a type of wood I have never burned before, I get excited. the real bummer about wood is that you have to season it so long before burning it. I have some 8 inch Pear trunk sections stacked up and marked (yes I'm a geek) for next winter. a month ago I bundled up a whole bunch of chopsticks I had hoarded for several months from our chinese take out and burned it....watching to see the flame.....the coals it produced...how long it burned....etc. I have my eyes out for a couple types of wood that while not abundant, do exist in my area. Shag bark hickory, Birch, Weeping Willow, ironwood. last year I cut up a large holly tree and tossed the splits in the stack without marking them....I don't know which pieces they are so I won't know how to evaluate their burn qualities. Jeez I am an obcessed dork. "no cash fun" . This is definately "no cash fun". of the "exotics" I have burned, Dogwood is probably my favorite. It burns super hot and leaves a magnificent coal.
