L.,
I have been in your position. I have 4 sons and homeschooled them until 2nd gr! I have my 4yr old son at home with me now. I help my husband in our business and I'm a real estate agent! I just moved from Atlanta and they had amazing homeschool groups there. I just wanted to mention Greenwood Park..if that is the correct name. You take Lake Mary Blvd off of I4 and come down to..oh goodness, forgot the name...but you'll see the signs for the YMCA! Turn R toward the YMCA and library and then take your first R after Lake Mary HS. The park is on the right and I've noticed a lot of kids at different times of the day..so they must be homeschooled. Great park too! So much to do. An enclosed hocket rink that would allow your kids to run and play and keep them in one area! :)
I am sure FL has some great associations for your HS needs. I really enjoyed these groups in Ga. I'll keep my eyes/ears out for you..I am always hearing of groups!
Take Care!
