#caving trip today to #PeakCavern in #Castleton. Had a lovely time, went to the sumps at both ends with a couple a minor diversions, including going through the duck a couple of times. Many thanks to the #DCA for the use of the TSG hut, the staff at Peak Cavern for putting up with us, and the #RubberDuckCavingClub for their usual wonderful company.
