Chris, it was raining so I got lazy after last nights cook and left the wind screen up around the WSM. The wind came up last night and this or morning, not hurricane force, but it was gusting pretty good sometimes. I put the coal shovel on the top to keep it in place but the windscreen stayed right in place. Didn’t move at all. And, at least with the top on, it acted as a good insulator as it was quite warm inside the screen.
