I recently joined the National Trust, which is a conservation charity dedicated to preserving and restoring places of historic and cultural interest and value in England and Wales. For the princely sum of £6.00 a month I now benefit from free entry to hundreds of wonderful places, from castles to medieval ruins, to wonderful gardens, areas of natural beauty and other amazing places. It's quite honestly the bargain of the century and I can't recommend it highly enough. Not only that, but I also get free parking too. I could still access these places if I wasn't a member, but the costs would soon mount up, as I like to explore! If this is your kind of thing then I cannot recommend the National Trust highly enough. Not only am I directly contributing to the preservation of places of historical and cultural value, but I am enjoying some wonderful days out. Do you have anything like the National Trust in your country?
