Parade
A bright colourful and noisy walk through the town.
Often used as a means to repay the local town for any help/assistance they have given to BJC
Try to make your parade exciting and a spectacle people would want to see, many parades are led by a Samba band and a section of people juggling, then a long dribble of people shuffling along behind. If you can work on getting the shufflers to look juggly as well it will make the parade look a lot better.
Maybe give the parade a theme (e.g. juggling pirates) and publicise this theme to convention-goers in advance so they can bring or wear something to fit with the theme.
As well as sorting out the logistics of getting the convention-goers to the start of the parade, you will also need to get permission from the council/police to hold a parade.
Additional complications can arrive because many town centres are now privately owned. an exteme example would be the centre of middlesbrough which is car free, but owned by 3 different companies, in order to Parade through that town would involve discussions with all 3.
