In the depths of winter (-30C today) we get to hankering for outdoor activities. We shoot twice each week in a school gym and try to keep things interesting my creating 3D challenges that mimic field and hunting conditions. Last night, I was shooting from a chair and thinking, wouldn't it be great to have a tree stand or tower in here. I was thinking about Sid's tower on the Border 3D range. Problem is, it has to be easily portable and easy to set up and take down. I think a step ladder might be a tad shakey. Surely some of you have come up with a solution to this.
