My family are Georgians for many genrations. We lived in S. Ga. as a child and I warn you-it gets real hot and humid! It will be a shock to the system from your time in England.
Yes, you’ll be able to hang laundry almost all year round and have a four season garden, too. I do here in N. Ga. You’ll have to look into which plants to plant in the Fall and which to do in Spring (for example, the onion family and garlic are better in Fall gardens down here and others you can do two plantings, like potatoes, greens and peas). If you have any questions about that, there are those of us here that could help you.
You’ll be able to visit Savannah and the islands off the coast there (good historical value, like Oglethorpe, too and lovely) and ya’ll will be able to easily get to Florida; southern Alabama, too has beautiful beaches.
Will you be close to Valdosta? I know a HS’ling from my Congregation that lives there.
