Apart form the Cam near Saffron Waldon does anyone know of any day ticket rivers in the Cambridgeshire area (or nearby)?

hi,
apparently theres a stream in Sawston behind the country store that holds wild trout, and is apparently free fishing. but i haven't checked it out yet. might be wrong.

Thanks, I know where the store is but didn't know about the stream. I'll try to check it out.

if you do check it out, could you let me know if its any good?
thanks.
