ATG Day 18- Slack Lining

well decided to use my ponysona for this one. I used to go slack lining a lot in the past. what is slack lining? tylically you stretch a 1 inch wide strap from one point to another usually between 2 tress, poles etc. and it is NOT drawn taught like a tight rope. It has a lot of slop on purpose and that makes it very dificult to walk on.
