@ Ratty and Mum
Ratty, please, you have absolutely nothing to apologize for.
I'm thrilled you and your Mum are enjoying the wonderful world of cryptic crosswords. As you'll no doubt have surmised from the number of responses your post has already elicited, you are not alone! and there will always be plenty of people only too willing to lend assistance, if and when needed.
In the meantime, enjoy the rest of your hike and we look forward to hearing again from you and your mum :-)
