This week's calls to action include the following events and activities. (All are free and open to the public, unless otherwise noted.)

Plan your National Night Out event

National Night Out Against Crime will be held on Tuesday, August 5. The Rochester Police Department recommends that neighborhood groups alert their community police officers as soon as possible if they are planning an event. The RPD crime prevention unit has resources to help neighbors plan a more successful event and attract more participants. But the resources are assigned on a first ask, first get basis. Information about event planning: 428-7640.

Free physicals for Rochester students

The University of Rochester Medical Center will provide free physicals for Rochester students ages 4 through 19. The examinations will be given from 6 p.m. to 8 p.m. on Thursdays, August 7, 14, 21, and 28, at the School of Medicine and Dentistry, 415 Elmwood Avenue. The examinations, which will be conducted by medical students, residents, and physicians, will be given to the first 125 students in line. Doors open at 4:30 p.m. Bring the name, phone number, and address of the student's primary care doctor, if you have one. Students under age 17 must be accompanied by a parent or guardian. Students who are 17 and are not accompanied by a parent must bring a signed parent consent form available at www.rcsdk12.org/Page/840. More information: 275-7203. Though the physical exams are free, parking is not.
