This guy is very informative and yes if the safety course is a no-no then def spend a lot of time in the parking lot and take extra time before you put yourself on a busy road with a lot of traffic or one with a higher speed limit.That's the plan. Going to work on those rights turns from a stop.
I've been checking out the youtube videos on it. What do you think of this one?
Gotta say this is one way to get that butterflied in the stomach at your age but more power to you bud just take extra time and try to ride at least once every day if even for a short ride, familiarity will give you confidence.
