Would it be weird if I went back to pick up airsoft bb's from an airsoft war I had 10 years ago?

Around 10 years ago I had an airsoft war in a forest with some friends. Now the forest has a fence in front of it. I started feeling bad about depositing all that plastic into the the earth so I was gonna try in get permission to go into the forest and pick the bb's up. I would have to tell them my story that I had an airsoft war 10 years ago and that I want to pick them up. Would that be weird?
