The walker - She thinks that any rule forbidding headphones would be unfair, asserting that walkers and runners have an equal right to enjoy the trail. A headphone ban, she says, would be misdirected, because it should be bikers' responsibility to yield to those on foot until a bike lane is specifically designated.
Unwilling to share the responibility for safety and apparently thinks cyclist should be banned from the bike path until they get their own separate facility. I have had too many walkers just do a U-turn on the bike path, right in front of me, with headphones on and not bothering to look before they move out of their lane. Same rules, same rights, same responsibilities.
