Thanks for your responses everyone! Sounds like we're all thinking along the same lines. Start 'em young and keep it fun!

We love the "what if" game. His interest in this started when he first watched Rescue Heroes on tv. He's always asking us "what if" and we turn it around on him and ask him what he thinks. It's fun and he retains the information much better when he's thought it through.

To answer your question Sue, I'm not homeschooling but close. I'm at home full-time with my son, and also take care of my nephew (almost 4yrs) and niece (2 yrs) during the day. The boys go to school half days. The preparedness geek (PG) in me was a big part of the reason I chose to leave the corporate world. I wasn't comfortable leaving my son in someone else's care when that someone wasn't a fellow PG.
