Choosing a location
All you’re really going to need is a fairly open space with structures that will allow you to wrap your line around. Trees, columns, poles, and really any two tall and sturdy structures will work, but I suggest finding two sturdy trees at a local park or in your backyard. The bark provides a little friction to hold your line stable and plus parks just rock.

Slacklining refers to the act of walking or balancing along a suspended length of flat webbing that is tensioned between two anchors. Slacklining is similar to slack rope walking and tightrope walking. Slacklines differ from tightwires and tightropes in the type of material used and the amount of tension applied during use. Slacklines are tensioned significantly less than tightropes or tightwires in order to create a dynamic line which will stretch and bounce like a long and narrow trampoline. Tension can be adjusted to suit the user, and different webbing may be used in various circumstances. Wikipedia®
