For me Local Guides is an expedition.
Sometimes I feel like an explorer of new lands, because I go to new (at least for me) plases, I explore these places, I learn what are these places good for, what can I do there, and what are the emotions I will feel there. And when my research is complete I can share it’s results with others, read their opinions about these places, discuss and rate it. Sounds like some kind of scientific research.
So for me Local Guides is a motivation to go to new places, to share my opinion, opportunity to get positive emotions and sence of life!
