Since 2014 "Wienerwaldtrails" pushes the Trail-Network in Vienna, Austria
After they built a Trailpark in Weidlingbach as a community-projekt, the are now going to build a new Jump-Line at the "Trailcenter Hohe Wand Wiese", based on crowdfunding.
Interesting approach! What do you think, is it possible to collect €50.000?
