I have decided to get all the 138 English and Scottish football league stadiums on OSM. It will take me months but I'll chip away.
Some local knowledge but mostly Bing tracing.
Done the A's on my list so far.
Adams Park, Wycombe Wanderers (http://osm.org/go/eus8~C2DW--)
Almondvale Stadium, Livingston (http://osm.org/go/evc~7xUzo--)
Amex/Falmer Stadium, Brighton and Hove Albion (http://osm.org/go/euq7FKbpg--)
Anfield, Liverpool (http://osm.org/go/euf9c2Gqv-)
Ashton Gate, Bristol City (http://osm.org/go/eukMSlLBl--)
One of these wasn't on the map and Already mass confusion on the names of 2 of them.
Linking to Wikipedia pages, operators, websites, adding addresses, Stands (sometimes at the moment as a separate building entity inside the stadium, still thinking of the best way to do this) among other info
I'll update the OSM wiki stub for stadium at some point to when I have seen the pitfalls/best way to map all of this.
