What was burning? And why hadn’t I heard any sirens? None of the smoke was black, so it probably wasn’t a structure or vehicle. It didn’t seem to be spreading, so it probably wasn’t vegetation. (There’s not much of that to burn anyway.) Passing vehicles didn’t slow down to gawk. Was this a regular thing, no big deal?
Part of me wanted to walk over to see what was going on, but the wiser part of me didn’t want to go stumbling around in the dark and end up skewered by cacti.
I guess if I really wanted the answer I could ask various official sources. But I think I’d rather hold onto the mystery.
