The swan war

I took the bike for a ride, though it was more like taking it for walk since very few people in this city are capable of making any room at all. There were a good many atheletes around. You'd think they'd be pentatheletes, but I actually think they were in training for an assault on the swan army I saw at the harbour. Look at them all!

I also saw a ninja but he wasn't very good:
