It would be nice if Niantic could define this.
I think it’s a great wayspot.
Maybe they’re saying it’s just structurally a part of a whole - a restaurant.
Like, I’ve seen the outdoor seating submitted for a restaurant. It’s not like a park picnic area you can drop into - you have to be a patron of that restaurant to sit there. The tables and chairs are boring, mass produced. In this case, I’d rather someone nominate the restaurant, even with a picture of its outdoor seating.
But for the silo, that one seating area is so unique! I’ll bet kids (and some adults) want to go there just to sit in the silo, lol. I see it more akin to art in a restaurant - eligible for “Explore”. If anyone can try again, I’d include “unique architecture” in the description.
