I also attended the event today. Overall I had an enjoyable day although I have seen most of the preserved buses before. I agree that spacing of buses was an issue early on although it seemed to improve throughout the day. 

For anyone interested Go North East brought:
3819, 3942, 6030, 6060, 6100, 6117, 6309, 4899, 4982, 6332. All Volvo except the contactless Streetdeck.

I enjoyed the shuttle ride I had on 3819 in particular as its been nearly 2 years since I rode a Go North East Olympian. This will almost certainly be my last chance as I heard that it will be withdrawn very soon, possibly as early as next week. I also rode on 6309 which meant that I rode on both the oldest and newest volvo's in the fleet.

So far I have just uploaded my Olympian photos but there will be more to come
