Tracey can fill you in on the gate but yes it is still ok to walk in.
Dave I disagree that the road has been "trashed". I drove it >12 months ago, before all the recent interest (as did you though perhaps you came in from the south end?). Then, as now, it was a bulldozed wasteland of sand. The only effect of climbers' cars has been to deepen the existing wheel ruts. Yes climbers have had an impact but the bulldozing is what "trashed" it not climbers' cars.
sorry to be pedantic but if climbers overstate our impacts then it just gives the "anti-climbers" (who DO read chockstone and ARE kicking up a stink about these crags) more ammunition, and they definitely aren't going to correct us.
