I wonder if wind turbine could possibly be eligible.
There is a wind farm in the forest and the wind turbines are an objective of trails in this forest, but i hesitate to nominate them.
From my point of view they would be great wayspot: hand made things in a natural area + an objective of trail + interesting for educationnal.
I don't have photo for now (never try to submit them for now) but this article is about them (to give an idea) https://www.facebook.com/alsace20.tv/posts/10155685051588652/
And the app Randéole on the app store and adroid store to see the trail about theses wind turbines.
I would like to have an idea if i can try to submit theses wind turbine and have a chance to get them validated.
