"but 50 years later, climbing into a Cub is not as easy as it used to be".
Why is that? I too, have been flying Cubs for over 50 years, and it still takes less than two seconds from flipping the prop to strapping into the back seat. I can't think of an easier plane to enter.
Hehe... what are your dimensions? Or you trying to be funny?
Cubs are made to be entered by 5' 100lbers
