So its like the annual Mephisto 'Ninja Parade' where none have been seen since its 1st year - something to sell column inches in the press to create that additional news coverage, following the adage 'any coverage is good coverage' ..apparantly.
Oh dear, the show organisers must be running out of ideas and abilities/funds to secure 'special/new/guest' A/C to ensure public attendance, since barnstorming and such antics are banned.
