Arlington has a lot of great public tennis courts 3 seasons of the year. There are however no public indoor courts during winter. Other nearby municipalities such as DC have courts that are enclosed over winter, those however are inconvenient for Arlington residents to get to. These need not be covered year round, could just enclose over winter like done at Hanes Point. Somewhere like the Wakefield HS courts would be good to enclose as they are set far enough back from any nearby houses that the tent structure would not be interfering with their views. A user fee could be charged to cover the cost.
