I always catch this one light at about the halfway point of my ride in. When it's cool out, my tanks get full. So, I casually roll over the light sensor and drift over to the curb (grassy median that sticks out past the stop line), put a foot down, lean over and give both barrels a good honk onto the grass. I figure that stuff is pretty top notch grub to some of the little beasties crawling around.

Bon appetit!
