RE: treestand or portable blind
Glad to see your taking your daughter with you. I have 2 that go with me every chance they get. My oldest (just turned 14) got her first one the day before her 14th b' day. She made a better shot than most experinced hunters make. She had never shot the rifle that we took that day and she made a perfect double lung shot at 153 yards. She was pumped... so was I to say the least.
I have a ground blind and after hunting with it for 3 years, i' m not convinced they are all that. I have yet to shoot a deer out of it. Keep in mind that I mostly bow hunt out of it. I f it were my choice and you have the means to purchase it AND hang it, I' d go with the double ladder setup. I don' t think you can go wrong by getting off the ground.
Good luck to you and your daughter.
