Thanks, Owen. Yes, I know you didn't suggest a hammer drill, but for the
moment that's the only thing I have readily available other than the
sledge hammer. I guess that if $60 and a day later I find that it didn't
work I'll try to duplicate what you had.

Eventually we're going to have to replace our front steps which will
involve a lot of cutting and splitting of rock and concrete, so I told the
XYL that we should just bite the bullet and go down to Home Depot and buy
one, and she told me to go lie down until the thought went away... :-)
