Last week all 6 of the places that I visit daily for catching wild Pokémon had their spawn rates reduced by about half. (Many of us have been chatting about that change on a different GoHub thread.) So getting double the stardust for catches brings me almost back to where things were.
For a whole week, woo hoo 
(after which it’s back to half, right?).
Still smells like 
to me. I guess I’ll need to use incense everywhere I go now…
