It seems disappointing but somewhat inevitable that we're expected to carry a mobile with us. One of the nice things about being out on the fells is to get away from the modern world for a few hours.
Guess I'll want to start looking for an ultralightweight mobile that I don't mind getting trashed by water (or worse- bog) penetration.
Not sure whether to enter this year as is the week before the Highlander MM and not sure how quickly I'd recover. Maybe the thought of carring a mobile will be just enough to put me off...
