As a facilities coordinator for the AAU basketball teams (GO, LA SLAM!) and a member of the Hilltopper Basketball Association (HBA), I can confirm that facilities for sports and recreational activities in Los Alamos are scarce.
Organizations such as youth basketball, soccer, volleyball, adult basketball, roller derby (youth and adult), pickleball, fencing, and martial arts are all competing (i.e. "fighting")over limited space.
Los Alamos is an active town, with diverse and varied interest. We have been limited by lack of facilities for far too long.
