I also have a juvenile gray tree frog hanging out in my garden, though my photo isn’t a good one. S/he has been near the kitchen door, perhaps because the lighted windows in the evening attract bugs along with the insects visiting during the day.

A couple of fun facts about them:

-The adults can change color, chameleon-like, to better blend with surroundings. If they are on a paler tree, they are specled lighter gray. If on a dark tree, they change to a darker speckled gray, and if they end up on a green plant, they turn green speckled with black.

-The males have a bright golden area of skin when the thigh rests against the side of the belly, and flashing that gold patch by stretching out a leg during mating season helps attract females.
