Actually, the most extremes of weather are found in the US, as are the most congested airports - try flying into Chicago during snow time or Atlanta in a thunderstorm if you don't believe me although as a neophyte PPL you really shouldn't be in these types of environment. I welcome mixing with you on the KLGB approach but there are limits!
Acquisition of handling skills is the paramount goal and the wise realise that the laws of physics have little respect for nor pay attention to national boundaries - in other words, go where the flying is cheapest with an eye on the conversion process should you intend to return from whence you came. A few hours back home with a local flight instructor is all that's required to become familiar with parochial protocol and fetishes.
