Just a reminder that it's the Barrow Hill Beer Festival on Friday and Saturday (15th / 16th May).
The setting - in an old railway round house - is one of the better venues, surrounded, as you are, by steam engines (some actually in steam) and other relics of that era.
Even better, there's a courtesy bus running from Chesterfield station to the festival. It returns by the Derby Tup, a well run Tynemills pub serving Castle Rock beers and loads of guests.
On your return to Chesterfield, you'll have had such a good time, you won't be able to see straight! Just have a look at the church spire if you don't believe me ; )
