Great that you are getting kids involved Aidy.
It's been generally rather too hot for game fishing even up here, but I did manage to take advantage of a wee spate last weekend and got a 6lber, fresh cock grilse, and returned it. My cousin lost a fish too, whilst at least 4 others were caught the same day on our beats which was encouraging.
The water all ran away very quickly although there were a few more fish caught on the Monday in various rivers near here, but it was very humid and windy, so I gave it a miss. More heavy rain yesterday, so I might give it a go tomorrow again.
