Hi folks, I've come to this a bit late this week and haven't finished yet (not being as clever as genehunt) but will plod on. In common with genehunt, I find people take part in things which I don't see the sense of - like modern-day angling: throwing out some bait by way of a forum post, then sitting waiting by the computer line to see who he reels in. Then re-casting later, but still no-one takes the bait. Bad luck gene, but at least it's warmer than a riverbank :-)
The "young traveller" is a youngster who rides around on a wooden base with wheels. The first 5 letters is a type of fish. HOpe this helps.
1d is a word for "having kittens" or getting worked up over something. A "N"(chess abbr. for Knight) in the middle of a word for "choosing"
How are you?
1d and 21d have been thoroughly discussed already on this thread - have a look back, then ask again if you are still puzzled.
12a It's a form a transport that only a fool (especially a young one) would attempt. It's made up of the name of a fish, followed by a term for someone getting on to a transport (of whatever sort).
Not able to get the RT till either Thursday/Friday now so rather late again and will be in the future. All done except I'm stuck on 16A. Had campari but couldn't connect it to the clue so presume it's wrong. Some help please but not the answer!
