General tips & NYPD regulations for a safe and fun march day

We are all incredibly excited for the big day and it can be easy to forget the little things. We want to help all our marchers be prepared when they join us and know what to expect from our friends in blue, the NYPD.

Signs, Banners, Props, & Balloons

If you have been working hard expressing your love for science with a sign or banner, please note that for safety reasons, NYPD won't permit signs affixed to wooden sticks or metal poles, i.e. anything that is hard. You will be able to use materials like pieces of cardboard, cardboard tubes, string - just not anything that is hard or could be used as a weapon.
We also want to let you know that it is against city regulations to tape your signs to any kind of public property, such as trees, light posts or police barricades. Or putting markings on sidewalks - permanent or not - is considered graffiti by the city. In other words, it is important to note that even using sidewalk chalk is against city regulations.
Remember this event is taking place on Earth Day and as science enthusiasts let's try to use recyclable material for posters - and please don't leave them scattered on the streets or in subway stations.
Balloons will not be allowed at the event.

Dress for the weather

Spring is here which means blossoming flowers and sometimes unpredictable weather. Make sure you check the weather reports and are dressed appropriately.
Keep sun protection in mind and bring your sun block, sunglasses, hat, and any other sun protection you may want.
If the forecast calls for rain, grab your poncho and leave the umbrella at home. Umbrellas will not be allowed at the march.
Wear comfortable shoes, celebrating your way down Central Park West and Broadway will be a lot of work!
Pack light; we recommend traveling with a small bag. Backpacks and larger bags are discouraged. Please also keep in mind that all bags are subject to search by NYPD for marchers participating in the event.
We've heard some really creative costume ideas and we can't wait to see them at the march! Just keep in mind that you will not be allowed to wear a mask or have any prop that looks like a weapon.

Food and drinks

We won't be selling any food or drinks at the march but the Upper West Side is full of great places to grab a bite. We encourage marchers to pack a snack and water, preferably in a reusable bottle. Need a coffee fix? Think green: bring your reusable mug and skip the disposable coffee cups. We are asking all our marchers to bring a small bag with them to keep their own trash in and take it with you. We have an amazing group of volunteers who will be working tirelessly after the march is over to be sure that we are leaving our city clean and beautiful and appreciate your help in doing your part.
Alcohol is prohibited at the event.

Photography & Videography

Everyone is allowed to use their own phones and cameras to capture the march activities happening in public space.


We think it’s great that Fido wants to come out and show his support for science, but this may not be the best environment for pets. This event will draw a large crowd which will include small children. How about featuring your well dressed science pet on your sign instead? Of course, service animals are welcome to come out to both show and be support.


Due to the large number of people expected to come out in the name of science, it will be best to leave your bicycle at home or locked outside of the event area. To best ensure the safety of all marchers, let’s stick with strollers and wheelchairs being the only wheeled transporter on the route.

Central Park

There is nothing better than a beautiful day in Central Park. Marchers will be allowed to exit the route and go into Central Park, but you will not be allowed to (re)enter the march through Central Park.

Keep it Green

It is Earth Day weekend after all! Please pack light: bring a reusable water bottle/thermos, carry your trash out with you, and have a plan for your signs after the march (once you’ve sent us your photos of course!) Some attendees have suggested a sign swap, which is a great way to share your support!
