It isn't just the fire. You may live miles away but have to deal with thick smoke for weeks. Last summer we had a fire In BC to the north, CA fires to the south, a fairly close fire raging in the Pasayten wilderness to the west, and fires to the east. It wasn't fun. I left for a bit to a still smoky, but not as bad spot, but I had to come home. That has happened for the last few years. I will get a headache the first day and then have a scratchy feeling throat for the duration. A lot of folks wear masks, but my nose is running so bad that it doesn't work too well.
I used to go out on fire crews once in a while. Even then, it seemed we could get out of the smoke for a while. Times have changed. I hope we have a damp summer this year.
