Of course this old oak is causing drama on Maple Street. Classic neighborhood stuff. @richard226 is right that cabling young trees makes more sense, but an ancient leaning oak is basically a ticking time bomb. Spending cash to cable it seems like a band-aid on a broken leg. If it's already that far gone, just take it down before it does real damage. Nobody wants to explain to their insurance why a tree crushed their garage. But hey, maybe some folks enjoy the excitement of living on the edge.
