Each year I organise a Beer and Guns day. We meet in the morning and drive to Bisley and take part in the NRA Open Day. After a day of shooting we leave, drive back to Reading and go to the CAMRA Real Ale and Cider Festival.
One particular year I delayed buying my tickets and they sold out. I am a member of the NRA [ NRA-UK not to be confused with the American NRA, which has done more damage to itself than any government could have done :) ] so I phoned the organiser and begged them to create an extra place for me. They said that's a bit cheeky but as I was actively promoting the sport by getting friends to come, they would make an exception for me.
The Open Day registration page displays the number of tickets remaining so I thought I'd put some of my super skills together to produce a graph of how quickly the tickets are sold, so I and others won't get caught out again.

It'll be interesting to find out if the sales behaviour changes year-on-year... yay more graphs for another day.
