Hi Eddie, me too ... I want to see what you come up with.
I wish I could send you Wesley's tree house with the tree !!
I'm sure yours will be a lot more comfortable though. You should have a great view with multiple shooting lanes from what I can tell. It would be great if you could get some power to it for some creature comforts like a heater or fridge. But there's a lot of stuff out there to make blinds more comfortable now.
I'm looking forward to your updates and photos.
