Some good friends have home schooled all of their children (6). Their youngest, a set of twins, graduate this coming spring. They participated in a homeschooling co-op. Whatever mom or dad couldn't teach, there was somebody available who could.
For enrichment, all children learned to play a musical instrument or took voice lessons (1-violin, 1 - guitar, 2 - piano, 2 -voice). Two of the girls played soccer for the co-op, two of the boys played basketball. One boy and one girl joined the co-op's little theater company, and performed in plays.
Of the four older kids, two went to college, two attended vo-tech. They lived at home to keeps costs down, while commuting. I don't know what the twins are going to do.
Their kids seem like they've done ok.
