There's a wood lot just north of Greenway Parkway at 16th Street called Bills Firewood. He's got a nice selection of smoking and camp wood, with the usual suspects, and also including citrus, alder, mulberry and walnut. Pretty conveniently located for many of us in the North Central corridor area. He's lookin' for about $40 for a wheelbarrow full. He's listed in Craigslist.
