Lets play a photo game

Hi all. I hope this posts, as I'm having trouble lately starting a thread.

I've noticed when someone posts a picture, that others sometimes post another of the same subject as part of their reply. I think it is cool that people may have archived so many photos, they are able to post a reply like that.

Anyway, I was thinking we could make a game of it. We could start with a subject, and people can post their pictures of that subject until we reach 5 pictures. The person who has the 5th picture can suggest a new subject, which he or she would submit the first picture of that subject.
I hope this sounds clear and that it doesn't sound silly.
I would like to start with A Horse Drawn Carriage

I hope you play along.
Dale.
