I have several ash trees in my yard, of varying age. The emerald ash borer is within striking distance, so I wanted to take the smaller trees out before the became infested so I can have the wood for the fireplace. I cut the first yesterday. I've felled trees in the past, but never within 20 feet of the house. Even though I know it will fall the right direction, there's a bit of a "pucker factor" waiting for it to fall.
But I think I'll leave the big one next to the street.
