In reply to Munch:
Sorry for being late to this, I know I'm too late but anyways: Most of Raven's scar dries within a day. Routes like 'Stratagem and Collateral' dry in about 6 or so hours. Over on the fever pitch wall, the routes take about a day to dry.
Raven is pretty clean at the moment, so almost the entire crag will be in good condition at the moment.
