Where at?

All over the region isn't it?

yy, theres always at least 85-90% chance of encountering one in shaking grass, just walk around near some grass patch and some of it should shake, can take a little while, but the xp is worth it

esp if the pokemon lvl ur lvling is under the lvl of the audino, then u get even moar xp

So there's no recommended place to do this?

the place with the highest lvl pokemon u can access

The route after black city/white forest is the best to use, cycle trough and around lvl 50 audino's I think?

Between Black and Undella?

giant chasm is a good place imo

both are good, giant chasm has higher lvled poke, but the route after black city/white forest is a lot more practical

oh
