drauk is quite right - flying overseas is excellent fun and experience. Las Vegas North airfield is a very busy GA airport - and the Grand Canyon/Hoover Dam is a must (as is "The Strip!")

As for South Africa - brilliant - and very cheap. Even Jo'burg has cheap flying from places like Lanseria or Mid Rand. Very odd taxiing at 5000ft+ and leaning the engine back! Lots of nice small strips to visit to:-

Enjoy whatever you do!!
