Bee Sentry

I was walking this morning and encountered this bumblebee that was just hovering over the no-cars-permitted road. For a solid three minutes it hovered beside me, moving in and out from the space just in front of my eyes as though trying to figure me out. I finally continued on my way to the home center and bought some stuff. When I returned, the bumblebee was still there. It swooped back in and hovered again in front of my face, as though in greeting.
