The Jerk Cook-Out was a bit of red herring (does that metaphor work?) in that the event was unticketed and had more reach and was more popular than expected or planned.

The vast majority of visitors to the Horniman travel by public transport - it would be a sensible precaution that the events stress the public transport options and limited parking.

I have no problem with the Horniman doing this - as noted above it's good for businesses in the area, and probably essential to the continued wellbeing of the museum, given the withdrawal of central gov cash for its operations.

As recent events have shown - its sometimes good to write with your support to a planning application - because otherwise the objectors claim that no-one wants the development.
