I don't know about the lump charcoal, but as far as BBQ Galore wood chunk selection it is pretty good. I don't have one where I live, but I drove down to Dallas once for work. I loaded up my poor Camaro with lots of wood. I know they carry Alder, Oak,Cherry,Apple,Pecan,and of course Hickory and Mesquite chunks. I found a local source for Pecan, but thinking I may have to make a road trip to Atlanta BBQ Galore to get Apple cause I love it and ran out a few months ago. If it is only 30 mins away I would definitely check it out to see if they have what you want, cause shipping charges will be insane.
BTW- Anyone know of a source between Nashville and Huntsville where I can get Apple chunks? I would hate to drive all the way to Atlanta to get them.
