Jo Ann,
WOW! Nice firewood stack. I am not sure if they are a good wood or not. It seems like they would burn fast.
One river birch can be pretty, but I wouldn't have one, or five, either.
Mika,
We have three walnuts and a silver maple. The neighbors also had two walnuts and they took them down. Their's had good nuts, ours don't. We do pick up and crack them when we get good ones.
Many many years ago there was a walnut shortage. I helped my Dad pick up from everywhere we knew there was a tree. They took them hulls and all. I got $25.00 for my help.
