I have 529 plan for my kids

I have been contribuiting to 529 plan since 8 years ago.  So far I am pretty happy with it.  And the account for my first child is big enough for public college now, he has two and half years to go before going to college, so I guess that we don't have to pay much extra for his college.  Even if he goes to a private school, the cost should not be too bad and we can easily afford it. 

The performance of California's 529 plan is not bad, at least in line with S&P 500.
