The Street Angels in Whitby are celebrating their fifth birthday today.
They're a group of 19 volunteers who help keep people in the town safe at night on weekends.
You can go along to their stall at Dock End between 10am and 2pm today, where they'll have cakes, cards and crafts for kids.
They're looking for more volunteers and at their stall today you can also find out more about how you could help.
Christine Koller, who's one of the Whitby Street Angels, said:
"We go out on Friday and Saturday nights from about 10 o'clock until 2am, depending on how busy it is. We deal with people who have had a bit too much to drink, we try to get them home, sometimes they just want someone to talk to. We give out flip flops, water, and we're all trained in how to do first aid.
I love doing it, we get good feedback most of the time, it's just lovely to be able to help. I really enjoy it, every night we go out it's something different, you can never predict what kind of an atmosphere it's going to be, but generally it's a nice atmosphere."
