The first activity in any country is likely to be putting up a flag to attract a few fans with the skills. Assuming the game is not on TV and there is not a large British or Aussie ex-pat population, that might not be easy in El Salvador.
A quick look shows that The Daily Mash are not too complimentary about anyone, we should be flattered by the attention.
It is a reminder though of how the game can seem. The defence is organised, so there are not big gaps and momentum is required is how we see it, big blokes bashing into each other is how it looks from the outside. The tackle and play the ball is a key contest for the rugby league fan and as key an indicator to the game as scrums used to be in rugby union, to the uninitiated, it looks like running into the big bloke did not work, so the game stops so they can try again.
