nothing really to do with amps and such. but, last winter i bought my moms house which was built in the 50's i believe. i did a bunch of remodeling throughout. i cut a doorway through the back of a cedar closet and in to the back of a regular closet. then built a wall to now have a huge walk in / through closet. anyway, while cutting through the cedar boards and cleaning up the pile of them, i noticed a message written on the back of one of the boards that would be on the inside of the wall. not able to be seen. if i wouldn't have cut open the wall, no one would have ever seen it. it said, written in pencil, "what size do you wear?". super creepy as this was the inside wall of a closet.
