Why be a member of a conservation charity? To visits sites they manage for your enjoyment yes, but maybe whether you can go or not it's also cos of what they represent, do & the things they protect. Don't drop out now cos you can't get your 'value' & when they need u most...
...Charities aren't responsible for Covid-19 nor are they accountable for the government guidance, or your interpretation of it, they're working within very testing times. We all have to take responsibility for our own actions, have some sense & humility. This is my personal view
And if you can't get to your fave site just now why not try some digital access to supplement your local exercise walks. So many great examples being put on by many charities.
