I don't know the answer to that zoo question...
so I will reply to the previous question,
that No,
the amount of time I can spend outdoors is not weather-dependent.
I am not able to spend more time outdoors, when the weather is favorable.
What is the main reason that the zoos, in Britain, are presently in danger of closing?
(I could guess several possibilities, but I am interested, and I do not know which is primary at this time)
