It never rains in southern California(well no more than 3 or 4 times a year), but it sure does in Atlanta. I'm definitely going to miss the sunny weather year round in LA. I haven't had to wear a coat since I left New York City in 2001.
It's going to be a huge shock to my system to experience 4 seasons again, although I must say I love the fall/winter season because fashion is always really hot during this time of the year.
So I'm bracing myself for the rain, the cold, and the humidity of the south, but I will definitely miss the constant sunshine in southern Cali.
