October- my favorite month of

October- my favorite month of the year. ..most likely warm and dry in the day and slightly cooler night, but not cold. Quite possibly Santa Ana winds and brush fires in the foothills.

This October (2018), however, has been incredibly uncharacteristic with two freak rain storms thus far.. no complaints here, though. I love heavy rain and lightening storms!
