There is a NC Cooperative Extension site (my computer won't allow me to post a link today) that says to plant them 4" deep.
Aha! It's working now but wouldn't work this morning!

"Plant the cloves 4 in. deep and 6 in. apart making sure that the root end is sitting on the bottom, mulching heavily to protect from sub-zero temperatures."
It's very confusing since we're both zone 7 (NC and Long Island) and yet we've always been told the standard is 2" deep.
