Oh bull pucky. It's always an option. It's just a matter of whether you want to or not.
I was able to send my kids to a low-tuition Catholic school, but homeschooling would never have been possible. We needed two, sometimes three paychecks to survive. And that was in the days of one car, no cable tv, no cell phones, no luxuries of any kind to give up.
Cool - sounds great.
My kids will have a good education, in our little refrigerator box down by the river as we eat out of dumpsters.
