I was homeschooled two decades ago, and I had a similar experience: some core classes were delivered via satellite (and recorded into VHS tapes), other classes were taught at a church, some were taught in other families' homes, one class was taught in a private school, I was a part of afterschool clubs, had frequent field trips, and did a lot of self directed learning. The freedom for self directed learning was probably the number one benefit I got out of being "home"-schooled.
