I'm already checking out the tuts and I really love your humorous teaching style.  Explaining magnets is a biggie for me and I'm sure for others as well.  A lot of market products (older products, anyway) instruct 'apply magnets' and if you don't know what that means the product may end up set aside and the money wasted.  

Thanks for the wishes on the Smokies.  The area is so breathtaking and reminds us of where we grew up, though nowhere near that scale.  It's just tough moving from one tourist area and heading toward another.  But at least we know what we're in for.  :)
