Below, an interesting map showing the location Mexican clubs. What a hurdle is geography! Imagine, clubs that are 3000 miles apart from one another ... where have we heard that before?
The guess here is the IRB's present Mexican census more or less approximates the density of American clubs in the 1930s, 40s, and 50s -- with the possible exception of New England -- once you adjust for the fact that America is approximately 5 times bigger by landmass.
And what has happened since then? Over the past 40 years, we've been busy forming new clubs at new levels. Equally important, we've developed proven techniques for growth in a continental nation, best practices for introducing a foreign game to the world's most crowded, sophisticated sports markets. This constitutes real achievement and heritage.
People who describe America as rugby's 'sleeing giant' either know comparatively little about our game or aren't thinking very hard.
