We have a couple of properties with power poles on them. The one in the above picture has just the one pole, and on the other, a power line runs through the property so it has many poles. After finding this hog rub I went and looked at the poles on the other property and on a couple of them I found rubs. So, it might be the creosote? I always carry a bag of corn with me (on my ATV) and spread it around places where hogs are to keep them coming..Although, they will keep coming no matter what I do...Here are the poles on the other property. The rubs were on poles down from this feeder.
