I'll be visiting 278 and friends on Friday as part of a long circular walk starting from Rowen on the south side of Tal y Fan; weather's looking dodgy later in the day, but I intend going nonetheless, fully prepared!
On two of my previous visits to Druids Circle I have required full weather proofing with horizontal driving rain putting it to the test, so should that happen again, it'll be nothing new!
If there should be anyone wanting and able to join me, I'm open to company; mail me, and we'll sort something out.
Cheers
Tim
