Got a lot of great plans for an elevated box blind, need help on deciding how tall, and size. Going to bow and rifle hunt. Plan was to put up platform with pop up on top, with a rail around for safety this year. Then next year frame in permanent. Was first thinking 6 x 6 on 12'. I bought shawdow hunter elevators. Now thinking 8x8 but only going 10 feet up, just a lot less cutting. Need some advice. When bow hunting deer are going to be around 20 yards or less.
