I am about to tear the vinyl skirting off of my mobile home and replace
it with brick. I intended to pour a concrete footing down to the
frostline -- 12" here in SC.

Two people have told me a footing is unnecessary. One says just to turn
the first row of brick sideways and on edge and build on that. The
other says as long as I have good red clay under it, just to lay the
brick directly on the clay.

Does anyone here have experience w/ this kind of construction on
Southern red clay? Is this sane or is it a shortcut I'll regret?

Thanks.
