Oxbridges of Konigsberg

A challenge for the cartographically minded among my readers:

What's the most efficient route for visiting all Oxford's colleges?

Method of transport: bicycle. No other restrictions except that you must pass the lodge of each college. Doubling back on yourself is allowed (despite the title of the post!).

A reminder of the location of all the Colleges can be seen on this hopefully accurate map from the University website.

ETA:

I do realise this is a hard problem (Owen says it may even be an NP-hard problem) but thought it might've been the sort of thing that you clever people had already done... like the "visit all the underground stations in a day" challenge, kind of thing...

KML

Has anybody else noticed that KML in Google Maps doesn't seem to work any more?

e.g. try this: http://maps.google.co.uk/?q=http:/…

For me, this example (very simple KML) shows my pointer, but the map doesn't show -- I just get grey tiles saying "We are sorry, but we don't have imagery at this zoom level for this region. Try zooming out for a broader look." Zooming out doesn't make any difference.

This used to work. We haven't changed anything. I can't find a single KML file on the web which does work in Google Maps. Have Google broken this? Am I going mad?

ETA: In fact, it's not just KML. Any search in Google Maps seems to be broken for me, e.g. searching for 'Oxford' -- it finds it, it shows the pics and so on in the sidebar, it puts a point on the map, but doesn't show any map tiles.

And while doing searches for Oxford I got a sponsored link from Google pointing me to "Oxford Homeopath". Grrrr. More than homeopathic amounts of map data, please, and fewer sponsored links to charlatans.

ETA 2: Really, no amount of zooming out seems to make the map appear for me. :-(
