Episode 93 of The Big Event is a both-feet-first jump into the 49-Mile Makeover. #TotalSF founders Peter Hartlaub and Heather Knight will be covering the existing 49-Mile Scenic Drive route on Sept. 4 by foot, bike, skates, bus - anything but a motor vehicle that they're piloting. They talk about their plans for a new route with reader help, air out the arguments they've been having and invite two experts — Kristine Poggioli and Carolyn Eidson, authors of "Walking San Francisco's 49-Mile Scenic Drive."

Produced by Peter Hartlaub. Music is "The Tide Will Rise" by the Sunset Shipwrecks off their album "Community."
