We have been out walking to green space near our home but keeping distance . No symptoms & we are in Scotland. If we had symptoms I would stay home.Whether it’s private land or not, it doesn’t matter in Scotland as we have the right to roam. Therefore she can meet members of the public anywhere, especially given that there is a clear path which shows people walk their regularly.
ETA it’s not a tourist green space just a small
Field up the road!
