In case you've missed them through other channels: there are now videos on YouTube about the Easter explorations in Fridge Door Cave and Mistletoe Pot. The 6 videos for each are listed near the bottom of each description page (http://matienzocaves.org.uk/descrip/1800.htm
). They're all essential viewing (!) but, especially recommended, is Jim Lister's video 4 with prospects for future explorations there and in Cueva Llanío.
