In reply to timmyhobby:
Have had some short heavy showers tonight but should be dry up to the weekend, so suspect there'll be a few bits here and there that are dry.
But if you're out on sandstone this weekend you really ought to be giving a hand with the clear-up at Harrison's.

Although fair enough if you're out both days to have one day on the work party and one day climbing.
