I am building a castle, actually a 10’ diameter tower in my backyard with rocks I “borrowed” from various neighboors (i checked w/them first) and quikrete. I also got about 300 bricks from a friend at school (it’s amazing what you can get if you don’t mind admitting that you’re a sophemore in highscool and you’re building a castle!). I hope to finish in summer ‘07, it should be about 10 feet high. This is practice for my real castle i’ll be spending most of my life building (it will be MUCH larger). I’m doing all the work by myself.
