Wow what a great week for the weather.
If you want to make the most of it this weekend, then I recommend the Hockney Trail http://www.yocc.co.uk/ The website contains the locations of lots of the Hockney paintings. I am looking forward to doing the trail again in the different seasons. It should really allow us to see how our lovely countrysides changes.
Whilst you are there you can go the the nature reserve under the Humber Bridge, there are some great sculptures hidden down there.
