Couldn't get a shot of the cavity filling (yes, I had a new chain on the saw), the concrete wasn't bad, but the bricks and rocks were tough to deal with.
I invariably have to deal with concrete, metal, etc. within 3 days of buying and installing a BRAND NEW chain on the big saw. I barely know what it is like to use a big saw with more than half the metal on the teeth any more! Seems like I can run a chain for months after it gets filed halfway down.
