When it came time to put my daughter thru college,
I found that money was the problem. Still paying off the debt.
My parents found that money was such a problem that they stopped paying my college after my first year. I had to quit mid-term. The college subsequently sent collection agents after me for the next few years (during the 70's recession, when I couldn't find lasting work to save my soul).
I'm glad money is not a problem for your kids, though.
Shame how CA Repubs think we spend too much on ed, when we spend less per CA student than most states. Less than freeking Alabama, last list I saw.
