The leafblower. The one sound that never ceases from 7AM to 6PM every single day. Gets intersting when there's a chorus from 4 or 5 crews at the same time, all within a few hundred yards of eachother. Hmmm, come to think of it maybe those aren't santa ana winds after all, just too many leafblowers going all at the same time. Seriously, thanks for dirty harry imagery and stay safe guys.
