Thanks for the good wishes, I'm on the mend. I've just hit a glitch with the medication, a visit to the consultant this morning look set to sort this.
This tiny stream in Derbyshire sounds intriguing, and I am try to guess which one, I'm guessing it's fairly near you and may have the initials MB. Some photos would be interesting to see.
I certainly would be up for some Grayling fishing, Lisa is happy for me to be out on the riverbank, but I think she would prefer for me to be out with someone else, not that I'm a liability and would require a risk assessment

and an ambulance on standby.
