Yes, that is an interesting technology and an interesting
alternative, Mark. It might be a little expensive unless you
know what you're going for will be worth it. Also, those core
drill bits aren't cheap either.
But that is a good idea and is a good beginning to a thread on
alternatives to explosives. There are some other interesting
alternatives out there and this would be a good place to
post information about them.

Thanks,
Joe

Thanks for the heads-up about the "ease" of using
jackhammers, hurricane.

I've seen that pic before. Pretty awesome!
And humor is always welcome. Just can't say for sure that
everyone on this board will "get it".
(See now, that was supposed to be a joke. )
