I was there too: it was an interesting day, not only because of the weather!
IIRC Alan's not too keen on hydration systems either (particularly those - mine - which leaked all over Abrahams floor!).
Hoewever, in spite of the rain and the wind (which conspired with the terrain to knock me over on the saddle between Maiden Moor and Cat Bells!), it was a great day out, even though I struggled to keep up with everyone on the uphill bits!
I meant to stay over and take a couple of further walks, but wasn't looking forward to another nights camping in the rain: then the wind blew the front of the tent flat, so I packed up and went home before the tent was completely falttened!
