After trawling this thread have come up with these two ideas for cheap and fun days out: www.treasuretrails.co.uk/ and www.geocaching.com/ - anyone any experience of them? I have dds aged 14,11,4 and ds aged 7. Have no money. Live in middle of a backwater (Lincolnshire) so no lively museum/gallery/stately homes to visit we haven't already done to death.
