Route 24

Route 24 is a route north of Cerulean City, and next to Route 25. Route 24 has a medium sized tall grass and it has the Nugget Bridge. Once you are about to enter, your Rival will challenge you. If you defeat him, he will give you a Fame Checker. There are 5 trainers on the Nugget Bridge who will challenge you to a battle. They will challenge you, one by one. After defeating all 5 players there, a disguised Team-Rocket Grunt will give you a Nugget. He will then ask you to join Team Rocket, and you cannot respond. The player automatically refuses the offer, and battles the Grunt.
