It sounds like we had some similar experiences in our youth. Your comments are spot on. Sandcastles is about a camp I used to go to with this group of friends every year. There was a specific moment, very vivid in my memory, that I wanted to capture. A really nasty thunderstorm came in off the lake and truly transformed the beach as I described. That moment watching my friend is something that always stuck with me. We used to go on hikes and take off for the day and come up with stories about the tree-people and whatever we happened to come across in our travels. I had a couple of friends who played the guitar, and some of my best memories are listening to them play and singing along. One of my favorite was Wish You Were Here, by Pink Floyd, hence the mention in my dedication at the end. Thank you for your comments. I'm so glad you re-lived these memories with me
