I do think that our visitors are now in the habit of doing walk abouts at least in order to acclimatise. All this surely for the day in which they do this in broad daylight which has to be soon.
In fact we have zero rreason to fear any alien visitors at all. They want to be good guests and they are definately tourists. Actual studies are an other matter and will be done in conjunction with our own folks as well.
Hopefully they all develop a taste for coffee.
