Yeah, basically just go to Kanto & make your way to Pewter City. Some random old guy gives you the Rainbow Wing, then go back to Ecruteak & go to the tower & the monk guy lets you by.
To get to Pewter City you'll have to make your way to Lavender Town to the get Poke Flute radio thing so you can clear that Snorlax out of the way just outside of Vermillion, then go through the Diglett Cave.
But I'll tell you now, Ho-oh is murder to catch. I eventually got mad & used the Master Ball on it.
