We've been camping and canoeing in the Norfolk Broads with the cousins over the bank holiday.  It was such fun - real Swallows and Amazons stuff.  I wasn't expecting to enjoy it as much as I did.  There're something addictive about stripping back your life to the basics for a few days and watching with kids run free without a phone or laptop in the background.  I might be persuaded to actually go again!
