I think it's always sad when someone packs in their own business, especially one which PD has put so much hard time and money. As a track day enthusiast, I did go with TTP depending what day suited work etc.. But I did avoid him, if possible. If there was anyone who liked the sound of his own voice, it was our Phil!
Never mind.
No hard feelings, good luck in your next career.( I suggest a safety officer, cause they really are boring)
