What do you do after beating misty?

You best the rest of the Kanto Gym Leaders. Since they are challenged in no particular order, Misty may be your Seventh challenge. If this is so, then you go to Cinnibar Island, where you find Blue...

Find the Machine part in one of the buoys and head back to the power plant. Then get the radio stations in Kanto from the guy in the radio tower. Then go to Diglett's Cave Entrance go on radio drag...

It's from just holding your hand.

I think that you get past Saffron city and go to Celadon City and beat Ericka that will be the best choice. ____ After Misty you go to Vermillion City to take on Lt. Surge.
