Thank you! I was hoping to build a treehouse, but a hurricane wiped out most of the big trees in 2003. Now it's all 6-20' tall Balsam Firs, which are too small

Thank you! I was hoping to build a treehouse, but a hurricane wiped out most of the big trees in 2003. Now it's all 6-20' tall Balsam Firs, which are too small to make treehouses in. Maybe in 20 years...
