In reply to Michael Hood:
Wasn't quite a day - set off at 5pm on the Friday, got to Fort William about 11pm; kipped out near the distillery (you could in those days); up to the north face; did TR & down No.4 Gully; I was going to do NE Buttress as well but my boots were hurting so back down to FW; something to eat in Nevis Sport (hence knowing about the 45min time); started hitching back, got to the services just south of Glasgow by about 7pm, dossed there and was home by about 11am Sunday morning.
