I 'liked' the Milton Keynes Play Association (MKPA) on Facebook at the beginning of the holidays and they have been putting a message on every morning listing all of the free events happening in Mk that day.
Today's update reads
"Today's FREE play sessions...
10am-12.30pm Bletchley (Leon Park)
10am-12.30pm New Bradwell (Newport Road Rec)
2pm-4.30pm Bradwell Common (Summerfield School)
2pm-4.30pm Kents Hill (Main Field/Next to Pavilion)
2pm-4.30pm Conniburrow (Next to Meeting Place)"
and
"Also today, the return of the ever-popular WOODLAND PLAY in Linford Wood:
Scramble nets, Zip Line, Nature Crafts, Bug Hunts and more!
Follow the signs from behind the BP petrol station on the V7 to the activity.
Come and join in the fun from 2pm-4pm."
I've already listed the Woodland play session on the 'What's On' but I hadn't seen the other ones.
They also have a website with all the details on here if you like a bit more forward planning.
HTH :)
