True enough.. Although disposing of that 2 ton block might be a bit
of a challenge. That concrete breaker they're using on the freeway
job would make short work of it. I saw them dropping pieces that
were the size of those concrete jersey barriers (15 ft long and 2 ft
high or thereabouts) they use for temporary freeway dividers.

Ahhh.. Not enough manual labor there.. dig it out by hand, and break
it up with a chisel and 4 pound hammer. That'll build some muscles. <grin>

No real risk with chemical anchors. The concrete will fail before
the anchor does if you follow mfrs recommendations (aka LXC prime
directive). I would (and have) trusted my life to chemical
anchors. The primary reason they use cast-in-place anchors is that
they are cheaper and easier, not because there's any structural
problem with them.
