anyone else cook on day trips, nothing like a bacon sarnie to boast moral and if you place yourself well enough you can troll others walking up the hill with the smell
Don't really see the point in doing this for a day trip, carrying all that extra gear and food seems a waste of time and effort when you'll probably be up and back down within 7 hours so may as well go and find a pub and let someone else do the prep/cooking/cleaning up for you
