We are at the Blackheath Mini's Festival today. It is at the location in the app, not the site we went to earlier this year. Expect this to end around 1pm.
Parking is going to be difficult, use side streets and follow marshals directions. Park carefully to avoid tickets. Get there early and further details to follow. You can bring dogs, so long as they are kept on a lead.
Wet weather gear, water, snacks and something warm to wear are order of the day.
