Take them to court i would. I would fight for my sport... They cant ban you from riding your own sport... just plead guilty to damaging the wall, you might geta fine for it... but, thats the most they gonna do... just plead that you dont have ANYWHERE to ride your sport... because the coucil wont supply you with somewhere... then the council will cough up... Thats what my uncle has told me to do if i get "banned" from riding, or the sort... (hes a police man...) lol
