Which way to enter??? Which are the 2 clues that tell you?
I can see reasoning for either way>>>
the one ending in G could indicate it goes "up and down" although this is the answer , not the clue?
OR the first of the ones ending in Q has "across" in the clue (If this is correct, which is the other clue?)
ok scorpiojo, thanks, I'll go with the "across" version and hope that someone comes along later to tell us which other clue is indicating the way of entry
