Because he doesn't need to, the track conditions and also when it happened to Vaciluk a few years back he didn't come back. Also Polish club might not be too impressed!
I think the issue is Oxford are the only ones doing the admission like this. As someone has said other events do it, mainly entertainment things like admission to bonfire/fireworks night and carnivals etc.
You also said about Zach going to Plymouth just to panic some Poole fans when you know it wasn't true! So forgive me for not believing you. Unless you want to give me some context
I think it was Riss who said he didn't like the Leicester track since they made changes to it but he did like it before. Though Leicester have made more changes to the track? Or is that just to improve the drainage?
