Ziplining has been one of my favorite experiences of my life and that is saying something. In Pittsburgh there is this course called Go Ape and it is a tree course that ends every section of wood courses with a zipline doen to the bottom so you can walk to the next course. I suggest doing this with a friends or someone you know because it is TERRIFYINGLY fun. Emphasis on the terrifyingly. Although you dont loive in Pittsburgh PA in the United States I suggest doing this anyway. Also as a point of reference the longest zipline is in Peru.
