I'm such a nerd. My dh bought one of those chain cleaning things and my chain is so clean now. This morning my back tire was flat so dh showed me how to fix it. He put an old tube, that he had patched, on and I was good to go. It feels so good to have a clean chain and know that I can (maybe) fix my own tire should I get another flat. Can you tell I am still new to all this.
