I shot a doe this sun out of my blind. Ihave the doghouse. To draw, I just angle towards the corner. Once I'm back i have room to aim out the window. I did this with my g/f in thhe blind w/ me video taping.
I don't think I would leave the back door open. I would be afraid that the deer would be able to see me inside. Another tip is to wear black. Its alot harder to see inside. BTW I shoot through the shoot through window with no problems.
