those guys dressing as batman and standing on public buildings get alot of publicity and get noticed - maybe some distressed banned drivers who've been caught for going miniscule amounts over the limit and totted up over 3 years could get involved in such antics? i must admit i am tempted myself. the punishment for going on say buckingham palace is so little theres not much to lose (much much less punishment than being caught 3mph over the limit 4 times for example!)
another thing i was thinking of doing was signing up the scamera partnerships PO box addresses for a load of junk mail
