don't wait too long.
Lady I work with has health problems and can't mow. The guy who'd done her yard for years is moving on to college(poor bastard), and the new guy recommended has disappeared. So she asked if I could mow it for her to hold it to a reasonable level until she can find someone.
Went over this morning. Let's just say that if the front had been much higher I'd have needed to find a scythe to go over it with before getting out the mower. Nice, thick grass damn near 18" high in a couple of spots. Finished cutting it, could have refilled my compost heap.
Now I need to pull out the belt sander and work on a couple of things. I shall endevour to return later with all my fingers intact.
