The journey took three hours each way including waiting around for buses, and the walk from Bolton bus station to the ex-mill the networking kit was in. Considering Bolton is only 25 miles away from Burnley, that's an average of not much better than 8MPH. I really need to get Fenchurch on the road soon...

Worryingly they looked like they were about to collapse in a pile of rust, and there was a faint whiff of leaking gas in the area.
