Yeah - I'm in too. Both ears - three separate and distinct sounds. End of a long day after things have 'quieted' down is when it's the worst. It's like the background noise from a spaceship in a science fiction movie. It is what it is, but it can make people suicidal so here's hoping they've come up with something.
The neighborhood I grew up in was full of houses with detached garages, all very close to one another. We would go "garage hopping" - get on one and then see how far we could go. Other times if was just garage climbing. Once I fell through the roof of a friend's dilapidated garage. Silly boy.
#3 - Robert Hansen (the Butcher Baker) is the subject of a fairly decent movie starring Nicolas Cage and John Cusack and is currently available on Netflix: The Frozen Ground
