Robin Hamman, blogmeister at the BBC (among much else) runs an excellent blog about Shedworking's home town of St Albans. He has also put together an excellent list of free wi-fi spots in the city. I know there are various sites which also provide this type of list, but they always seem to be a bit hit and miss. If you know of similar ventures to Robin's (i.e. properly detailed free wi-fi spots) around the country, please let me know and we'll start up a list.
