What will freeze?
I have a 28' that I keep in the water on a small inland lake in North Texas. The weather is usually fine. In fact I went out for a few hours yesterday afternoon. There is a cold front that has come thru (29 degrees) and I noticed a few people putting heaters inside their boats.
What can freeze? I do not have shore power or water. I have maybe 2 gallons in my water tank. Portable john is empty.
Is there anything I should be worried about other then the 3 "cold ones" I left in the galley?
