Eclipses happen every year like clockwork (it basically is clockwork, but on a huge scale). Eclipse seasons are spring and fall, around the equinoxes. You could very easily fly to see a total eclipse every few years if you want to, because we know when they are going to happen and where will have totality - it’s very routine stuff. There’s literally nothing special at all about the one that just happened, except that a lot of people haven’t seen one before because it hasn’t happened -at that location- in a time.
So no, absolutely not something you’ll never get a chance to see again, tho you won’t be able if you go blind like a fucking moron.
I’d just like to also point out that pretending this is designed to be accessible is a joke when 90+% of the population doesn’t use mobility devices at all and thus this bench supposedly caters to an intensely small subset of the population who doesn’t need it or want it (I’ve never heard wheelchair folks ask for benches; they ask for ramps..), and it functions less well for everyone else as a result. Need to care for a child on the park bench? Too fucking bad.
The epitome of “the cruelty is the point”.
