A passion flower vine has crept along a chain link fence, completely upholstering the fence with leaves, buds and now flowers. You can smell the scent from a half block away. One particular type of big, slow bumble bee has found the vine. They ignore me and work each flower, their backs covered in bright pollen. Two or even three bees can share each flower for a short while, never bothering with territorial squabbles. They have a job to do and there are more than enough of those heavenly flowers to go around.
