My son plays for Trowbridge Under 7's and we are looking forward to the local matches this Sunday

I think Rugby is great for kids. My son does both Football and Rugby and in my opinion there is no comparison.
The Football in Westbury is pretty much a shambles. No structure, little organisation, last minute advice of any games or cancellation, no facilities (apart from a portaloo that should be condemned)
The Rugby is fantastic! In Trowbridge (and I am sure in all the local clubs) the coaching team is SO enthusiastic and patient with kids as young as 4yrs who haven't got a clue. In last week's victory over Corsham, one of my son's team mates actually scored at the wrong end (again). They are taught discipline but also have a fantastic time. The club has a comprehensive website, with team news, fixture listings and match reports (with photos).
They have played tournaments and matches all over the South - including beating Bath Under 7's (!) - and always finish with a game of Bulldog for both or all teams. The kids are plastered in mud, exhausted and starving - so every club lays on hotdogs after the game.
My son just loves playing sport so we will continue supporting him in both these activities, but I hope he chooses the rugby route!
