Three men with reflectors on their clothing are searching in the field.
Some men wearing orange vests are working the nightshift to clean up garbage at the park.
The man could have been wearing yellow clothing instead of orange vests. They also could have been searching in any field during the day instead of cleaning up a specific park while working the nightshift.
