When there don't forgot the low bowl barrow 100 m to the SE, there seemed a real connection between the two when i was there, take a look at baza's picture [ lodge park longbarrow 3 rd picture] and i think this shows that well, and i just went though the side gate around the winter solstice, they aren't stopping me visiting the ancesters, it's a great place and i'm surprised it isn't more well known.
