When we moved here about 36 years ago, there were eight or nine big red and white oaks over the hill. Over the years, all but one bit the dust. I was cutting the grass today and noticed a lot more sunlight coming through the woods than normal, then I saw it - the last big oak (white) went down in the past few days. Lots of rot on the trunk - I never suspected it and the tree always looked healthy. There is one more this size behind my neighbor's house. On the bright side, there are lots of young uns coming up - 10" - 20" dia. and I have some primo firewood to winch up the hill. Probably put on a rope and try to take the stress of the one that's doubled over before I do any other cutting, it could spring back at any time. The main stem will stay there, simply too heavy and it will make nice homes for some of the wildlife.
