I happened across your website tonight and truly wish I had found it sooner. I love the book mobile , i was fortunate enough to have one a few years of my childhood. I really love the lecture topics and have a few questions. 1.Are past lectures available for download? I would gladly pay a small fee for them. 2.How long are the lectures? Very willing to drive from Easley SC to attend a few. Could possibly donate time as well.
