The Thames is not traditionally the prettiest river but it has its moments. Here it is turning pink in a sunset this summer. Its the reason the city is here and I like how in moments of real importance it rises to the occasion. For the golden Jubilee the queen floated down it with hundreds of boats, it was an amazing sight, like vikings setting out for battle. Good river spots - North Bank Savoy Gardens, Royal Festival Hall.

Southbank has organically evolved into a place of cultural significance through the persistent creative use of skateboarders spanning over generations. Southbank is currently under threat of being destroyed and replaced by coffee shops and retail outlets. There has been an alternative skate spot preposed to be built under Hungerford Bridge, this at first glance seems like an appropriate solution. Unfortunately this undermines the grassroots movement that has been developed over the years. Skateboarders have utilised the unsuspecting angles of brutalist architecture in a way they were originally not intended, in doing so they have created a space that is special and unreplicable. You can help save this historic place by signing the petition.

An unassuming glass door on an otherwise plain facade hides a cavernous space, with high ceilings and huge sliding partitioned walls producing excellent exhibitions in a space you'll want to go back to.

A Hint of Mint, Taylors Sky, Class Freedom, Horseshoe Ping – amazing names, muscle, speed, beers, the cheap thrill of Greyhound racing at the dog tracks is a London must. It was best experienced at Walthamstow Stadium, an iconic 1930's stadium with a fantastic neon sign that sadly closed for racing in 2008. However fights to save it from demolition and reopen it for racing have been ongoing since then. So please support the campaign 'Save our Stow' and in the meantime head to the dog tracks in Romford, Wimbledon or Crayford.

Half a mile from Markfield Park down the River Lee is Springfield Park. The park rises steeply up from the river and has an amazing array of tree species making it beautiful in all seasons. At the brim of the hill there is a line of park benches each one surrounded by box hedge offering a private view across the Lee Valley, Walthamstow and beyond. The park warden was nice enough to give me a chestnut log a couple of years ago from which I carved a bench and two stools.
