So true,

If glow power were no longer an option I would simply walk away from whatever was left.
The hobby is also about the people you share it with . I have little in common with the new fly it out of the box type.

Compared to the effort invested in designing and building a plane, even a kit built plane; Obtaining fuel is minor. For a person who pulls their latest creation out of a box and flies minutes later, fuel must be a near insurmountable problem.

A trip to the flying field thirty years ago was an event in itself. Loads of real creativity, Real builders who could truly appreciate those efforts as well.
The fuel? No problem. Never will be.
