Well, Accyman, it's your own fault for throwing out your calendar.
It is very informative with pretty pictures and all collection dates. It even has a form you can fill in with your 'helpful' comments on their services. Printed on recyclable paper too.
Would have thought, with you being computer au fait, you would know that you can access this calendar on line.
Go on, try it :
Hyndburn Borough Council - Refuse Collection Search - Search
BTW.... if you had a Christmas tree, this will be collected in Oswaldtwistle and Knuzden on 17th January this year.
