Sling shots sure bring back memories. I grew up with wrist rockets. We use to shoot allot when we were kids.
I have several DCOs on my place in Minnesota. I am surprised they have survived our winters but they are 3 years old and about 4' tall. I just took them out of their tree tubes this year and caged them, the deer were eating all of the top growth. We will see how they do the next few years.
