I think its good to escape from the office for awhile each day and especially when the weather is as nice as it is today.
On of my favourite haunts is the Jubilee River. Its also a great nature reserve in its own right. I have been visiting it for a year now and you get to see the full cycle. Lots of gulls and terns, young chicks now. In the winter you can see plenty of Redwing and Fieldfare. Look out for Skylarks too!
