hmm, I'll have to find a decent way of keeping things dry in Kerry up a hill beside the sea.
Mayo is basically the same sort of thing as Kerry, and we'd get sodden turf dried out. If you get something covered and off the ground, with air able to move through it, on average it's going to dry out.
For the turf once you get it in off the bog you'd just pile it up haphazardly into a long triangle, and then tile the nicer longer ones pointing inwards on the outside of the bank. Then you could kind of quarry the loose turf from within the bank, it was normally fairly dry even though the bank would be uncovered.
If it was really pissing down for weeks you'd have a backup stash in a shed though.
