With Matt, Brockers and Duncan.
It was as wet and mucky as expected.
As I drilled the required holes, 4no. 550mm x 12mm, and sorted stuff out, with Matt's assistance, Brockers replaced the skip on the long haul and then, finally got the better of the last boulder in Tuck Shop. Meanwhile, Duncan took the opportunity to explore the rest of the East Series and completed the round trip before returning to help haul my kit out and the fragmented rock from Tuck Shop.
Everything done, the evening was brought to a satisfactory conclusion. The rock was left at the base of the entrance for another day.
