My younger siblings did end up in some sort of group homeschool PE class. My mom tried a few things before finding that, which apparently was nice. I put it in the "pro" category only because I think I would have really hated PE. I wouldn't say my life was completely devoid of physical activity, just probably less than average.

If your parents wouldn't have been fundamental Christians they could have given you much better books.

Agree, but it's my understanding that most homeschoolers do so for religious reasons. I trust the average LWer to do a lot better on this score than the average christian.
