The term refers to narrative of human activities with some potential for physical danger, an exciting or unusual experience, bold; an unusual risky undertaking, with uncertain outcome. For the legend, no adventure is outside the realm of "possibility", it becomes a major pursuit in and of itself, a means to an end. Or a new end to a new beginning.
"Life is either a daring adventure or nothing."
Legends are most often passed on person-to-person by storytelling or through written text, but here, they're passed on through documentary video.
Our first ADVL is of forty-some years into riding dual-sport motorcycles all across the country, where uncountable miles were turned and epic travels were had.
