I live very close to the River Tweed, Ettrick and Yarrow.
Apparently some people pay tens of thousands of pounds to fish for salmon on the Tweed, more so the famously named - Junction Pool near Kelso.
Many celebs fish the Tweed, Chris Tarrant is a regular.
However, beats me why anyone would pay thousands to catch a Salmon but then im a country guy and living near famous rivers heavily congested with fish doesnt hold excitement for me, right, im off to teach a worm to swim which will be supported by a nice shiny treble hook lol
