The ending wasn't very conclusive. Put yourself in snowman's position. What would you have done? why?

This is a pretty dark dystopia. After Snowman replenishes his supplies, he heads back to the arboretum. The Crakers tell him that they have been visited by three people like him. Snowman follows his fellow survivors' tracks to the beach and sees them sitting before a campfire. He is about to approach the trio as the novel ends. I would have probably done the same thing.
