Interesting reading yours and Soup Dragon's proto-crawl. I agree with you about the start and finish points - this is one crawl where the Spoons is too far from the station to make a convenient meeting place. And the Brunswick opens at 11 anyway, so who needs Spoons?
The Little Chester micro is perhaps a little too far out - especially with the Coach & Horses acting as a kind of substitutes bench. It's half a mile from the Peacock and then another half mile to the Furnace afterwards.
Suggested route:
Brunswick (11 until 11:45ish)
Smithfield (opens at 12)
Exeter (wild card: Tap)
Peacock
Furnace
Five Lamps (wild card: Horse & Groom)
Mr Grundy's (wild card: Greyhound)
Golden Eagle (if thirsty on the way to the next pub!)
Flower Pot
Dolphin (wild card: Silk Mill)
Babington Spoons
Alexandra
That's 12 plus wild cards, so possibly needs a little trimming, or some pubs relegating to wild card status. I've left out Falstaff and Bell & Castle from my original suggestion, as too far away from the others.
What think you?
