Its usually only in Boylston for the three week course for DT Instructors. Check the MPTC website for upcoming classes, just had one in May, might not be another one til next year. Contact Dave Standen, he is the coordinator.
I am sure you must have heard of the current state of our MPTC. All classes have been frozen, and 3 academies will be closed, as a cost cutting measure. You can call Cadillac Duval and thank him! If you are not aware, see the Hot Topic thread.
