Good point for all South Floridia Freepers preparing for an extended emergency. Keep them from freezing and keep the mosquitoes off ;-)
Actually, a wool sweater would still be good. Its not always going to be warm. Especially after night fall. If you’ve been in warm weather all day, and temp drops to 80 at night, it can feel cold. Add wetness to that, and it can be worse. Thousands of people die of exposure even in warm weather. Never take the environment lightly.
