I just wanted to give a great big Thank You to David Levitt, owner and his crew at Sierra Cycles in Sierra Vista, AZ. We first contacted him in November of 2017 to ask about doing Spyder workshops AND to bear the printing costs of the event. He was unhesitating in his support. Those who attended the workshops I think were very pleased with the results; I know the one I went to on RT oil changes was very informative and nicely done. They use Amsoil, if anyone is wondering about that.
