I have all the old traps in my gun room and office at my shop. Trapping has been a passion of mine since I was a kid and still hit it hard every fall. Pre bait your area, have your trap with the doors open for a few day and then drop the doors and add in a few judas birds. Let's just say I have a few places to trap that guys would give there left nut to trap. I trap em, box them in computer boxes and grease the service elevator operator and load in my work van. My traps are 3'x3'x 6' high with perch bars. My spots are prebaited, so I have my guys bring in a 5 gal bucket of feed and ask the office mangers to toss feed out on the location. A nice lunch or day at the spa goes along way. I can do 3-400 in about 3 hours.
There's plenty of history in those boxes. Number 5 on ring 3.
