You've all said what I thought. I was the one with the two rucksacks. We were on a two day trip, so our rucksacks had spare clothes, toothbrushes etc, not just the normal day walk stuff.
The four men just said hello as they passed.
We might have taken them up on an offer of help. My friend had a dislocated shoulder from a slip on the scree near the top of Red Pike, and we had been descending for about 90 minutes (very slowly!). She preferred to walk down rather than try to summon rescue to the mountain (even assuming we could have got a signal to summon help!). We had managed to get a signal about half an hour before we met these chaps. Although the ambulance service are not supposed to send ambulances to wait for people, given the remote location (Buttermere) they had done so, based on our estimate of us being about half an hour from the valley floor. I would have either asked one of the men to go back to the Fish hotel to reassure the ambulance crew, if they arrived before us, that we were nearly there, or to carry a rucksack and escort my friend while I went ahead and waited for the ambulance. It would probably have taken only 15 minutes of their time.
As it happened the ambulance did arrive just before us, but my phone again had a signal so I got the call they made to check where we were. So we came to no harm due to their lack of help, but it did seem to both of us that some offer of help could have been made. We would have done, had the positions been reversed.
Friend now has shoulder arranged as it should be and is back with her family.
And a final moan about Davies taxis in Keswick. We were booked into the YHA in Buttermere, so I went on there after the ambulance had taken my friend away to Whitehaven. I booked a taxi for the following morning to take me back to my car at the north end of Cat Bells. Fifteen minutes after the taxi should have arrived I phoned to enquire - they had no record of my booking, and were now booked up for several hours! I started hitch-hiking, and some lovely people keeping track of a DofE group gave me a lift in their minibus almost to my car. As it happened I could have walked as friend did not get discharged from Whitehaven until about 3 pm!
(Sorry, turned into a bit of a moan!)
