Only having attended one quickbuild, I can't say I enjoyed it. In fact, I was playing with some left-over wet concrete and burnt my hands with it (it's pretty acidic stuff!), and then I started playing with some other building materials and one of the older Elders came along and gave me a resounding smack across the buttock region! No, it wasn't fun at all! (I was a kid @ the time)
