Oh, well if you haven't been to Route 16 then you can always stop the NPCs since you didn't battle them yet! :)
So far no Pokemon encounter, all items for these dustclouds :( Btw, do you know what's a min PID frame I should aim for? Like, if I take 100 steps, what's the lowest PID I can hit (Because walking where wild pokemon are advances by quite a bit)?
