As enjoyable as Summer rugby is I don't see how it could work long term. As Boots has already said, the summer is when people take their holidays, kids are off school etc. In the winter their isn't anything else to do, but when the weather is better in the summer people take their families for days out etc. Also, a number of pitches become cricket pitches in the summer or are closed to allow them time to recover from the winter months. There are already a lack of pitches across the North West so if rugby pitches are unused in the winter they will become football or RU pitches. Leigh Rec has already lost a pitch to football.
I agree that a possible break in the season would be beneficial as it would hopefully avoid the brunt of the really bad weather, but would also allow the pitches, and the players

, some time to recover.
