We're in Florida right now (Florida Caverns State Park) - North of Panama City. We are returning home Saturday after Christmas (to Indiana), provided the State Park does not evacuate us because of flooding. Anyway, I was planning on winterizing before we left on Saturday, but considering the warmer temperatures at home right now, I may wait myself. This would give us a better option to stop at another campground half way home Saturday night.
But, if following the weather from the local television stations back home, if the temps start to drop, I can always pull over, into a rest stop, or even a gas station, and "do the pink" any time. Trailer has a battery and will run the water pump just fine!
My advise is the same for you. Watch the weather at home (computer, I-phone, however), and if it looks like you're heading back into freezing temps, just stop and run the pink! Problem solved!
