This dragonfly, which I think is a Common Whitetail, was going back and forth between a patch of grass and a sidewalk, perching for 20 or 30 seconds in each place.

He might have been overstuffed with mosquitoes as there was no shortage of them after me.

ID corrections welcome.
I first thought it might be a Banded Pennant, the described variations on each species are confounding.

I think you are right, Ellen, about this being a Common Whitetail, a female to be more precise.
Thanks for that confirmation, Mike. I have seen them around off and on, but one of those that rarely stay put.
