Red Lion, I can't remember the directions offhand. However, for the Bees in the Wall:-

Turn off at the junction for Duxford. Take the turning for Duxford village (the turning AWAY from the air museum) - if you're driving south then it's a left turn at the roundabout, if you're driving north then it's a right turn. Turn off the roundabout SLOWLY, bcos you need to take the left turn about 50 yards further down the road! Take that left turn, and head down the country lane for about 5 minutes without turning off anywhere (beware the sudden corners!) until you get to a T-junction. Turn right at the T-junction, then right at the next T-junction, and then the Bees in the Wall is the pub on the left. It's about 5-10 minutes from the M11 junction.

If you want to sling me an email (spam.proof.graham.bartlett@pitechnology.com, minus the "spam.proof." - call me paranoid! :-) then I can give you further details if you want. Or I can give you references in StreetMap or MultiMap if you want. I can probably also find you directions to the Red Lion if you like.

Graham.
