Hi, Rusty!
I am back home!
It remained fine whilst we were out - but very black clouds overhead now.......
Thank you for the parsing.
I did not see "dox" sounds like "docks". I was looking for "dox" to be a part of a longer word, so beginning.
Yes, I can see "modem" now that you have kindly explained it.
But 12d.... I had "end" for "tip" - but didn't see "alter" for "reform" - a nice touch, I like that!
I'm not sure about "leg" - I agree with you that it is short for all those terms but am not convinced that is what is meant?
This may be pushing it a bit, but could "leg" be a "stage"? meaning "that must be taken"? (as worded in the clue)
Probably I am barking up the wrong tree........
How is your cycling progressing?
