Don't know why I dig it, but I do. I've always thought that February 29 was the coolest day of the (every fourth) year. It's kind of like when you fly back across the international dateline (west to east) and land before you took off. It's my own little version of a rip in the time/space continuum. Or at least that's my juvenile take on it. : )
Either way, Happy Leap Day!
