DJK Trolling indeed, although not Frankito. Southwark's parks don't open uniformly at 8. DP is open before then (at the village entrance). Ditto Belair. Burgess and Warwick Gardens are always open. Lambeth's Ruskin and Brockwell are open from about 7. Southwark could, with good management, and at no extra cost, ensure they're all open roughly at sunrise throughout the year.
