Currently working on a truly unlimited event. Two unique airports some distance apart (though the distance is less than my US caps tour), both on coastlines. Start from either and fly to the other, use any aircraft you like - prop, jet, commercial, military, GA, water based or land based, even airships (if you have the patience), and any route that works for you. Only restriction is you must make at least three stops along the way, anywhere you like; for water based aircraft the stops must be somewhere you would expect to find fuel and lodging.
