Free car parking on Saturdays from Lewisham council

Hi. For the next two Saturdays leading up to Christmas, Lewisham Council have said their car parks are free to use. This doesn’t include private one’s or street parking, but I still think this is very groovy of them. Not many councils are so generous.
