Brimful.

A meeting in Banbury and a reasonably early finish meant a pleasant drive back through Oxfordshire marred only intermittently by a wanker in a Range Rover or some chinless arse on a horse.
A small detour in Fairford always allows me a brief stop to wonder at this little piece of paradise (the River Coln) - one of the fishiest spots I've ever seen and absolutely alive with trout and grayling.
Chalk streams like this need a full aquifer to thrive and by the looks of this the aquifers are fine for the moment.
