I would say the Pacific Northwest. Say Portland or Seattle. Most of the rain occurs during the winter. The summers there are great and last I was there Washington did not have income tax (Portland is a bit high but they also do not have sales tax, less relevant in these days of internet mail order though).
since im here now, the gloom does get old. but the summers really are awesome out here. lots of hiking, skiing/boarding, lakes and all that only an hour from seattle -- closer if you live out of the dt area
people do rant about the gloom -- but its really just something you get used. just make a point to get out and exercise, stay proactive and you'll get over it. if you live in some very hot and humid place you'll be holed up inside because it's way too hut and humid -- it'll be just as miserable but on the opposite end of the spectrum... and at least with seattle, you can go out and play/hike/run in the drizzle
back to the OC -- what's it even mean to have no personality? so it's just a bunch of housing developments full of corporate workers commuting into LA? there's literally nothing going on there? you're right by LA right... so you can hit up the concerts, clubs and whatnot in LA right?
