The OneInchDreams-team organized a beautiful Slack-Festival this summer at Hochkönig in Austria. There were set up a lot of nice lines (for example the "tractor-longline" and two Midlines starting from a ski-jumping hill). It was really nice to meet so many funny and motivated people.
To get there a friend and I went there by bike, which was sometimes hard but a good experience, and training, too (450km in 3 days with min. 15kg on the back ;P).
