You guys are lucky that you haven't had the smoke until now. On Sunday the visibility here was about 5 miles. I could not see the mountains south of town, and on all the mountains around town it was not possible to pick out details on them. It's been really bad here for over a month now.
I live near Broadus and I checked the sky and there was a big plume of smoke all afternoon and there was and probably still is a fire around 25 miles Southwest of Broadus, according to the people I talked with who have land in that area.
