60 pounds or less? I thought big sledge hammer would shatter them;
wrong! I have more time on my hands than money at the moment.

Go down to the local Gym. Find about 20 very muscular gay men that
lift weights. Invite them to your place and let them bang each other
on the concrete. You'll end up with a pile of sand. It should be
easy to find these guys in SanFrancisco.
