I feel for you guys that are suffering, we had the same thing here on our east coast last year. We left to be safer from the fires, then came back a few days later. Driving into the pic below, I think I only got out to check the animals before we turned around and headed away again. The trees in the distance are about 100m/300' away! There were a whole heap of illnesses etc. that came as a result, even in people in the cities a fair distance away - you can't escape it really, even inside with the doors and windows closed it still gets in.
On a more positive note, I didn't harvest some exotic (for me
) trees that I've passed many times on the side of the road. In one section I have wild plum, black locust and desert ash, plus at least 2 different species of elm not far away. I did stop and do some tyre kicking, but it's right on a busy road and I'm not sure how a bit of handy work with a saw would be received, people get funny about trees even if they are a weed type
