Another garden centre.This time in search for vegetable compost for the new raised bed. These woods are nearby and just happened to have a "lockdown orienteering course ". That's why Mr P was so keen to come too. A regular orienteering course has large red and white flags. The course had been set up with bits of yellow and green stripey insulation tape attached to a twigs at each checkpoint site. Very difficult to spot in dappled sunshine. Spend ages, doubted my navigation, went off on wrong paths, found this ruin which helped me work out where I was.
