Guided by my experience as a volunteer to maintain a trail at New York New Jersey Trail Conference and my practice of drifting and encounters with trail markers, I became interested in how the sign of a trail marker guides me to open up a new world of signs and language, both physically and virtually, across urban and natural spaces. I am also interested in how a sign in general functions as a way of talking about the expression of wayfinding systems and the memory/experience across the different visual languages of space. Involved with my interventions towards different environment in this project, I am also thinking about a trail as a metaphor of the psycholinguistic structure of “entrance-body-exit” in our daily life.
