Always remember the guy who introduced the Otter back into our rivers in the UK, Philip Wayre, he ran an Otter Trust on the Norfolk/Suffolk border on the River Waveney, I visited here a few times, sadly the Trust is open to the public any more but his work still flourishes behind closed doors.
There was one Otter that didn't like getting wet would you believe so that was kept at Earsham, but to see these creatures just having so much fun is truly magical
