I'm in Connecticut, so yes lots of snow. None this year so far knock wood. I used this blanket when nights were 30 to 40, so that should work well for your situation. There are no holes in it. Just some fringies where the seams are. I can take a close up pic if you want.
I don't know how much shipping would cost. It doesn't weigh much, but on size alone, I'm guessing it would probably be at least $10 to Florida. I can check on that if you're interested. I take paypal if that works for you.
