Frontier-6 (1980)

You visit frontier towns as you go around the outer track, and you can buy up parts of them (bank, saloon, etc.) to secure revenue. Whenever you visit the Bank, you have the option of holding it up, in which case the game switches to a different mode, which uses the inside of the board. This shows a map of the Far West --you are now an outlaw on that map, running for the border. Those of the other players that want to are also put on the map as bounty hunters. Once the chase is resolved --one way or another-- the pieces return to the outer track.
