As many area photographers (and painters) know, this is the time of year that several fields of sunflowers located near Poolesville, Maryland come into bloom. They are located in McKee-Beshers Wildlife Management Area and are accessible to the public. I was out there yesterday to check on their status and the flowers need a little more time. Three people who were also inspecting the blooms advised me that it would be about a week before prime time.
The above photo was taken last year on July 16 in the field that is easiest to find (the one I checked yesterday) which will give a sense of the scene to those not familiar with this spot. Further information can be found at the Maryland Department of Natural Resources. The page contains links to two maps showing the locations of the fields.
