After earning my Private, I went on to take spin training (then
Aerobatic Training).

Just because it's not mandatory - doesn't mean it's not a good idea.
More new pilots should realize the value of continued education - and
find ways to get it.

One story about a Cherokee or Cessna getting tossed by turbulence or
jet blast/prop wash might get their attention.

Keep in mind.... It's really your ass up there!
