No I wouldn't (for the reasons quoted above). I was more addressing the notion that there has been a recently lifted ban on non-essential travel (though looking quickly I cannot see the post where it was mentioned so it may have been edited). There has never been such a ban. Before May 13th the "reasonable excuses" which people needed to leave their homes would not include spotting. After 13th May the non-exhaustive list was widened and people have been allowed to travel near enough where they wish for reasons which would certainly include spotting. They were (and still are) asked to consider other means of transport before choosing public transport, but that's all.Would you class a busy station, particularly one largely indoors or underground, as a 'public open space'?
