My favorite year for streets was 2008, and I can place very easily why. It was VERY immersive, houses flowed into streets, and the 6 scarezones for the most part were very fun and strong. The fact that they had 4 unofficial zones was great to me.
I like that this year there is an actual "Roaming" horde, but I feel like 5 streets, with 1 unofficial scarezones isn't enough. I get why, and I don't think the event will ever revert to that much street again due to operations, but it was fun while it lasted and I'm glad I got to see it.
