1. turn to a junction .... some kind person thinks it is G+O+A+T. but for one of the clues... cockney warmer I thought that was coat ---nanny goat. maybe i'm completely wrong.
Should point out that 'Cockney warmer' is to be read as 'Cockney more warm' = more 'ot = 'otter. All the other suggestions look good to me, possible exception being bison, unless the clue's a bit suspect. Can't suggest anything better though...
