What do you guys usually do with them? I currently have a 4x5 plot in the top left corner of my town full of X stars each with a gyroid buried in it. At the time, I had a bunch in inventory and didn't want to deal with them (and literally forgot you could sell them to retail) so I left them on a 4x4 (they increased later as I TT) plot above ground near my mayor's home but when I asked Isabelle about citizen satisfaction she said "some villagers feel like it's like living in a junkyard" so I knew it had to change and just buried them all in a corner.
