I texted him and says he be home about 2130hrs.
Made it for 2200, even without stopping (or actually sticking to the speed limit for that matter) sat nav was still over ambitious with the arrival time.
Shame I didn't think of it, or know of his itinerary, could have met him for a coffee on the way through.
I wish I had known what was happening too, a roughly thrown together plan involved a bus at 2200 on Fri, walk to tube, tube to tower, walk to fenchurch st, train to upminster, estima pickup to south ockendon. I knew where I was going but not really when I was going there and not entirely sure I was heading the right way most of the time
From there the only thing I could say for sure is that I would be heading North and most likely on the m6
Since my phone had decided that it's going to ignore 4 bars of signal and declare there was no service what there was of my vague plan ended up in the air.
Next time I'm down south on a daytrip I'll try and organise myself sooner (and better too)
