It might be in Oxfordshire David, but over here in Gloucestershire one might think they are trying to reduce the 'salt mountain'. I've even seen them salt the roads when the forecast temperatures were not expected to drop below 5C !
Agreed on the dehumidifier though. My garage also is not exactly airtight. Handy to keep some of the extracted water for steam irons, batteries and combined with anti-freeze for vehicle coolant systems...
