Greg, I'll call you today. You've been MIA for a while bro!
I felt the earthquake last night. The bed started vibrating and I hadn't even put a quarter in.
Serously though, I thought maybe my dog was at the foot of the bed scratching or something... nope. It also sounded like a machine was downstairs... kind of a low vibration or rumble. Barely noticeable IMO. Weird.
