Question

When I use fly or check my map, there is an excamation mark next to the route name, but only routes 35 and 33. Any idea what this signifies? (it's not the legendaries, they're else where and only route 33 has rain)

Answer 1

That means there are trainers on Routes 33 + 35 that you registered in your PokeGear that want to see you to battle or give you an item.
