We found this beautiful Highline spot a couple of years ago. So we returned to the location with a drilling machine for the bolts, ropes, slackline, harness and all of the other safety equipment. It took as all day to set up this line ( 17m long and about 30m-100mh high ) and we wanted to start walking the line in the morning. It rained all night but we gave it a try. Got out of bed at night, hiked to the line at night and rain, rigged the line...and were lucky.
