Ah Ha, I never knew that about temperatures in the 40's, it's that cool down period we do not normally have. Although we did have a few freezing days over the past two winters, temperatures that stay below 40 for long are rare out on the sea islands. If it gets cold it would only be for a few hours in the early morning, 5 to 9 am, then by mid morning it warms up. The sea water stays around 55 in the winter here and that helps too.
I imagine fresh garlic, no matter the size, would surely beat the grocery store stuff we get in the small towns of the south. Whenever I visit the northeast I buy this huge, juicy, fresh garlic and bring it home. I can't imagine what the baggage handlers think when they smell my luggage.
