Step into the time machine and relive some old-school jank. Purposely built to counteract the more sanitized flow trails in the area, Yer Sister offers a more precise slow-tech experience as opposed to Your Mom and Deliverance. Check your speed when you get into the open hydro cut - it's looser than you think This trail holds up very well in the wet.
