Sara,
There is a home school on base, I will dig the info up for you. Sometimes it's listed in the panarama. Here is one group and the lady does scholastic books, but she is a very good resource for all that is homeschooling! There is also a family P.E session that is made up of almost all homeschooled children at the fitness center. It starts up when school starts so if you go to that class you'll find a wealth of information through the mothers there. They do a lot of book swaps and things when groups of mom's give away the books/cirriculums they aren't using anymore. Check at the fitness center i guarentee you'll find people that LOVE to help out other moms.
I have the name of another mom who is just a fantastic resource. I will see if she has a contact number that she's willing to give out. For now here is the link to the address. If you call the number at the bottom of the page she'll help you out and give you a ton of info. She's very nice and very helpful.
