RE: tree stands and hunting partners??
Depends on the size and density of trees you could either have 2 hangs in the same tree or very close in seperate trees. My buddy and I sat together this spring hoping to video a bear being arrowed and were so close we could hold hands almost(2 seperate trees). Another option would be FRS with ear buds, if the area doesn't let you get close enough. Many FRS have voice activation and are a reasonable investment. We use this set up when calling elk and moose..it works marvelous(as long as your within range..in this case I don't see a problem).
Just some suggestion for yeah, good luck to the whole family...BTW it is great to see it is becoming a family sport...cudos!!!!
