Just so I'm clear on this.. You have to pay this guy to cut that monster down? That's the shortest 5' diameter oak I've ever heard of too...
Wait, so your not interested in paying this guy for the privilege of cutting down his likely hollow tree in his yard and cleaning it all up? Are you nuts ? I bet sorting though his stack of offers is keeping him busy.
I'm no pro, but I'd pay to drop it on his car. The guy might get leery as my accomplice videos the felling from the driver's seat of the running vehicle.
Or a least a member of a group of lunatics that like to cut and hoard wood. Oh wait......never mind! Gary
