Been to Portland Basin Museum today with the children. If you live in Greater Manchester and have never been, it's well worth a visit. Passes a few hours and is very interactive plus I learned loads of new things about where I live:
1) hills biscuits were made around here
2) the war song Tipperary was created by a bloke from round here
3) the first chip shop in the world was established not far from here!
See, there you go!
