Topo122: Topo from 'topography'; 122 from the former number of the Ordnance Survey 1:25,000 Explorer map covering my local area (now replaced by OS Explorer OL11).
My principal interests are local history and geography, covering Sussex, the Wye Valley (in particular, the villages of Hewelsfield and Brockweir) and the Isles of Scilly.
Occasionally I have a go at tidying up random Wikipedia articles, principally those pages categorised as missing a lead section. It's taught me a lot about the foibles of Wikipedia.
