Trip-S. is a term used by local skateboarders on the southern coast of western australia which refers to a weekly event at the albany skateboard track; the sunday skate session. The session starts at three pm every sunday; hence the 'Trip' in Trip-S, also gesturing a link to the three 'S's in Sunday Skate Session. Trip-S. is widely appreciated in the area as it brings together local skateboarders and endorses the saviour of the dying culture of 'old style' skateboarding.
