Who knew that just south west of Oxford is an area of worked-out limestone quarries that have since become picturesque nature reserves? That was the most enjoyable destination for a gang of gallant walkers under the careful leadership of David from Abingdon. Beginning at Wooton, where we wandered through an area one member dubbed 'bungalowland', we followed a figure of eight track round Dry Sandford and back to our start point. Highlights included the quarry sides, which are dotted with the nests of masonry bees, and also, we were told, with fossils. In addition, the quarry floor is criss-crossed by babbling streams and many boggy areas which provide a diverse habitat for all kinds of wildlife. The day was fine and we enjoyed an agreeable lunch spot. At the end of the walk there was a pub stop on Boar's Hill which had fine views of the plateau below. A rather more dubious attraction was an officious looking community speed watch campaigner whose speed gun will hopefully have had no unfortunate consequences for any of those attending. Congratulations to David (and his very capable helpers) for very successfully leading his first walk. Here's to more in the future!
