The Sheffield Farmers' market has changed timings, it is now on the 4th Thursday of every month from 09:00 to 16:30, still on Barker's Pool.
This is I imagine good news, there will be much more passing trade on a Thursday so hopefully this will mean more sales and therefore the economic development of the market. Bad news for people who don't work in Sheffield during the week and for me who up until today was unaware of the change and so expected the market there today.
Thanks for the info! :)
