I noticed scratch marks on the bottom of our boxes this morning. They are sitting on 6" bricks, with the openings facing east. On the back is a row of trees with the creek right behind and below. We thought that was the perfect location because of the proximity to water and the protection from afternoon sun. It looks like we have skunks following the creek who have come up to investigate the boxes. I'll need to set them up higher, i guess. A month ago, stores had half size whiskey barrels cheap, but i doubt I'll find any now.
