I was looking at some pictures of bait sites and saw that some had their barrels standing and some lying and the holes were in different locations.
I wish I knew how to do a pole but this is the best I can do.
When using a bait barrel do you have it lying down or standing up and where do you put the hole (top, bottom, middle, end) and what size hole do you like use and of course the most important question why do you use the setup you use.
I stand mine up chained to a tree so it can't move and the hole is 6 inches from the bottom and is 5x6. Why, because the bait is always pushing down and available (I was not sure if the bears could reach the bait with the holes at the top) and I was concerned about rain getting on the bait. Either that or I read it somewhere.
I look forward to your answers, as I am always looking for a better mouse trap.
