i didn't have my glasses on when i took the pics, i should have gotten a picture of the whole area. i'm not sure how thick the ceiling is , it used to be the roof before they built up a A frame roof on top. it seems pretty thick. its about 12" up from the floor, which meens a lot of up and down an extension ladder. the lighting is very poor in that area. its in a liqour distributors warehouse. i'm trying to decide wether i want to try it or not. if i do it i would have to drill a hole so i can get my inspection camera in there and see exactly where they are. i would cut a larger enough part of the ceiling out so i could work comfortably. if it was an easy to get to hive, i was going to do it for free for the experience. i told them i would let them know and if i didn't do it i would give them the name of someone who may, but it wouldn't be free. they want them out of there soon. they did me 2 bottles of wine for my time
