If you care at all about tennis in this country, The history of tennis instruction article written by John Carpenter is a must read!! It's the most interesting thing i've read this year. Go to find a tennis coach.com scroll down to MTM library, click and you'll see it. John takes you through the history of US tennis teaching and points out the problems with it. You hear about the mistakes of Bolleteri, Macci, and the many self promoters who have stunk up the profession!! John points out the mistakes and also the cures. GREAT JOB JOHN!!!!
