Thanks Sandi, I see one forecast for a low of 33 on the 5th. Good thing I've got the propane heaters. Even on the 4000btu setting they keep the insides plenty warm. What's bad is that the Weather Channel shows it to be in the 30s when we get to Progresso, Mexico. As far as I remember it's never been that chilly when we got there but it will be in the 80 in Cozumel.
