Photo made it look worse, seems to me some much smaller ones were worse for smoke and heat from flames, and I really waited until wind let up., Unfortunately my ugly mug can't be blamed on brush fire smoke.
Seriously though, the truck and bus traffic belching out black crud really did end up making me sick with a cold and chest stuff. Had read of others similarly affected, and Guatemala was the worst, vehicles often in terrible shape and chucking out diesel particulates like there was no tomorrow.
