''It will never be full'' - twice! Now that did make me laugh! I think you just need to witness a Bank Holiday weekend on the roads or try parking (legally) in Keswick on most fair weather weekends, or witness the rubbish left in remote locations. It is overfull already, I don't think there is a single SSSI in the Lake District that is classed better than 'fair, deteriorating'. Anyway the BG is small change in the great scheme of things, though the anti-clockwise route was a lot less obvious when I did mine in 1985...seems like yesterday...ish.
