Quick dash to Sump Two to celebrate a birthday
@JonnyC: Good pacey wander down the short dry, ladder left rigged by previous group, duck through into Two along to the sump, few pics at the sign, then a dash back to the surface via the wet way. Good to get out on a social trip, water not high, but fun still.
@RichM: A welcome trip, good to just cave in good company with no pressure. Couldn't seem to get enough air at times, subsequently found out that the group we passed in the entrance series had the MCR gas detectors with them and there was only 18% oxygen! Photography failed - flash + water doesn't mix.
