I live on a lake; my smoker is +-200 feet from the shore. It's too large to move around, so in answer to your first question; I dont move it. Regardless of type of wind and/or direction, it stays the same.
For the second question, I use fairly large VERY dry (and warmed usually) splits. It's RARE that I use an unsplt limb section.
Hance - Lake Dogs Cooking Team - MiM/MBN/GBA CBJ and comp cook
Lake Sinclair, GA (strategically about an hour from darn near anywhere)
Started competing in chili cookoffs back in the 1990's and have competed in more than I care to count. I became a CBJ in MiM in 2005, then MBN and in GBA in 2010. I've probably judged 130+- BBQ comps (sanctioned and unsanctioned) over this time. That said, I really enjoy competing more than I enjoy judging, and hope to get back to doing 4 or 5 a year in the near future.
