So many questions, I'll try and answer the best I can.
The cad program is called 3d-home architect. Its super simple, and really good.
The blind is in Missouri, Everything else is "G-14 classified"
As for the water, we'll have all we can stand come October. Last year the water level was boot hight INSIDE the previous blind. (Hince the 7' floor)
We're not rich by any means, we're just tired of standing in the water with waders while its 5 degrees outside. I hunt every weekend of the 60 day season with 4 other guys. At least one of us goes home early with a leaky pair of waders, per year. I can tell you first hand; THAT SUCKS! This way we can get to the blind just before sunrise, start breakfast, and stay all day if we want. AND STAY DRY!
Yes, we do have a ****-ton of brushing to do. However, this blind isn't the biggest one in Missouri. The key to big blinds is building in a treeline. I have hunted out of blinds a lot bigger than this. 3 story blinds are very comon in Arkansas, and you're pretty much guarenteed to shoot. It does take alot of willow trees to brush them.
You would be suprised what you can do with 5 people throwing down money, and helping build. We are 3 weeks, and $2,000.00 into this project. That is including building materials, various tools, hardware, and SEED. I highly suggest it! I just can't wait until it gets cold.
