Mind, given some of the comments on social media you wonder why Arriva bother rocking up. Any effort to attend these things (at extra cost to the operator, and often at the expense of driver rest days) should be commended - or we'll reach a point where rallys stop existing at all. 

Same goes for GNE, Stagecoach and any other commercial operator. Especially given how entitled some enthusiasts are these days, wanting to be in and around all the buses at all costs.
