I think this thread is another good example of how people in this hobby can help each other by pointing things out that is not always obvious to everyone.
Glitzers observations, stemming from his line of work, is something I would probably not come by, as I rarely have the chance to wander deep into forested areas (and when I do, I do not make many observations because I have to keep an eye out for my two little girls ("No, Anna, you CAN'T have a bronze age grave in the garden to play in!")).
Great stuff!
