Rural: What, when, where

The airwaves will be buzzing on 10 May, which is National Mills Day. On Sunday, the Furness amateur radio society will operate a special CB radio event from its headquarters in Gleaston Mill, an 18th-century water mill whose origins were in the Middle Ages.

There are about 400 wind and water mills open to the public in the UK, more than 60 of which are in working order. The special event radio station (call sign GB2GW) will make links with 80 to 90 mills both here and abroad.

Last year mills from The Netherlands, the Republic of Ireland and South Africa took part. If you're not a CB fan, you can watch the Furness clog dancers, and take in a converted cowshed, and view an archaeological dig (Mesolithic), as well as examining the clasp-arm pit wheel, the largest in the country, as you watch Gleaston Mill in action.

Gleaston Water Mill, Gleaston, near Ulverston, Cumbria (01229 869244, http://www//.watermill.co.uk), is open 10am-5pm, admission to mill pounds 1.50 (accompanied children free on Mills Day)
