Is there any old drivers like myself still on the go remember parking on Tower Hill waiting for a return load, IIRC The phone box nos were Royal then the number, There was 6 of them on the left opposite the little wood hut cafe, You could park overnight for free in Goodmans Yard St Katherines Way, Or pay to park on the National Car Park near the Royal Mint, Happy days , Have a drink in The Crooked Billet, The Brown Bear, The Long Bar, Plus many more, 
Regards Larry.
