Heading out into the country on a 4 lane highway, traffic's doing around 60 mph, as I am & I see an elderly woman standing on the grass medium. She looks, lets a car pass & starts walking across. Crosses the first lane, looks again in my direction & starts walking across my lane. I'm wearing an orange jacket, on a red motorcycle & my lights are on. She doesn't see me. I was watching for it & eased on the brakes as she took her first step, checking my mirrors to make sure I don't get hit from behind. I stopped 10 feet from her, she turns to see me & the look on her face said "I'll need a diaper change when I get home." She hurried across & I continued on. Hopefully she doesn't still drive.
