OK, maybe I've got bats in my belfrey, but I never thought I'd have wasps up my tailpipe!   It was difficult to photograph, but if you look closely you'll see 2 of mud-wasp nests I discovered recently.  There's a 3rd one behind the other 2.  The nests are vacant; I can only imagine the seriously brain-damaged inhabitants leaving in bizarre, irregular flight patterns before plummeting directly to earth.  The curious thing is that my motorcycle is only parked outside at work. I guess I need to talk to my boss about the length of my work-day...
