The first Professional Driving Xperience (PDX) of the year at Road Atlanta will be in July. This is an event where you get an instructor to ride along with you to teach you braking, shifting, and steering through the curves. There are no pace cars and you're allowed to run up to 95 MPH, though many in the event I participated in last November exceeded 100 MPH. This is a great method of honing your skills, whether it be negotiating the curves during Run For The Hills, or the expressways of Atlanta.
Registration is now open.
