Last Sand Castles of the Year

It was unseasonably warm early in October this year, so I was able to get to the beach and work in a couple more days of castle building. I'm not into things that look so much like medieval castles as I am into things that are tall and skinny and defy the notion of a pile of sand. My castles tend to fall a lot while being built. Here are the last offerings of the year, I fear. Unless it stays really warm.
