To be honest, I am a bit exhausted right now. I threw my back out and am just now getting back to normal. Im trying to take it easy for a bit. I usually have a hard time taking it easy till Im stuck on the floor. Ill donate a swarm or two to the feral population if I have to right now. That said, I have read about the double screen board and it sounds like a good Idea. Some day Ill get around to playing with it, Some day I hopefully will have all the gadgets and toys I need, ready for when the time comes that I can use them. Like extra boxes, bottom boards, and telescoping covers, inner covers, frames with foundation, nuc boxes, gas, money, fences, fencers, double screen boards, ............... I do have extra honey supers, lol
