Hi Andy
We may run something similar to the CPC this summer, where entrances are rigged, but its very unlikely to be in May. We're currently waiting to see how things pan out over the next couple of months as well as trying to work out why our membership wants from Gaping Gill this year.
Once we decide something, we'll update the website and I'll post on UKC if we plan on rigging anything and if that rigging will be available to other cavers to use.
Thanks!
Ben Wright
(BPC Treasurer)
