Well I moved from San Diego to Sarasota.
I miss a great deal about san diego. Ideally if you can get your ass in bed by nine get up do you chart work and be preparred by 530 or 630 San Diego would offer afternoons of surf or golf or whatever. But I never got to sleep early enough, so I was killing myself over time with lack of sleep and bad preparation.
It is a lot easier on me now and I feel healthier.
But if you can get enought sleep, San Diego is great. Now if you could have rental properties and move around and live in Forida 6 mos and a day. Perhaps you could set up the ultimate life style. San Diego, Lake Tahoe, Florida. That is my goal. Because there are a lot of great things about San Diego I miss. I am bummed I will not be surfing with my boys as they get older. San Diego's proximity to mammoth is great. It is 6-7 hours but as a trader if you get that bug up your butt or they get a great dump you can go at any time.
Finally, the weather. As far as year round climate, it really can not get much better. I did not need air conditioning and you only need the heat at night.
Now San Diego has a down side too. But for me the biggest relative problems were that I could not get to sleep early enough and the taxes. I was also concerned the price of my house might drop if I had not bailed.
As far as girls, If you are a good looking guy in great shape and have some cash, you will find some great looking women. But you will have a competition. If you are an average guy, you better import the women or know a good online dating service.
