I'm in the same boat. Luckly an inlaw rents, and sells generators from his shop. He said today he was 1 of 2 stores in the Calvert County reagon that had any generators left. My brother got one from him big enough to power 3 houses. He has to tow it home. He said he has a small one for me that is big enough for my refrigerator, tank, and maybe a tv. As of an hour ago I heard their were around 60 people waiting in line for a delivery truck to come to home depot up by DC. The had a few on that truck that people were waiting for.
good luck, I know I will need it. I live back in the woods. I almost have to cut up a tree every time we get a big storm anymore. I think it's because of all the rain this year. The ground is so saturated any wind stronger than 30mph seems to uproot trees.
