Where are the Bees?

Now that I have lots of flowers blooming and vegetables filled with blossoms, I've been watching for honey bees. Yesterday I finally spotted one. My tallest sunflower had a visitor. Lack of bees has me concerned.

Because honey bees fall under the nuisance category for life in the city hives are not permitted. How are urban gardens to thrive without bees? One more law to examine. One more opportunity to educate people.

Wasps sting, bumble bees sting but honey bees just move around me in the garden. They don't feel threatened and they have a clear goal so why would they attack?
