I still can't find that wine bottle, I think I have to consider it a loss. The only thing I can think of is that maybe I DID bring it, and I took it out of the cooler to make room for more ice and probably forgot it out, and somebody must have passed by the campground and took it. Though I don't imagine theft is that common at that place, I had solar panels out and everything, those are worth way more than a bottle of wine.
Either way, I have 3 bottles in the fridge, and a bunch of coolers, so plenty of alcohol for a while. I don't drink regularly but like to pop open a bottle of wine as a treat once and a while.
