I've noticed a pattern with my dad and that he drinks bourbon when it's not too warm out and/or Thanksgiving and Christmas weekends. Something my parents do during the summer is is let neighbors know what the weekend drink is to encourage people to stop by: Margaritas, Hurricanes, Mojitos, piña colada, Pimm's cup, different varieties of gin for Gin and Tonic etc. and frozen daiquiris and margaritas.
ETA: I just thought it was a cool idea in general to get people together. I'll be doing that someday too.
