When humans had seven fingers per hand bowling balls had five holes, pianists stretched their fingers across multiple octaves, and it was still possible to count to 14. Ponder possibilities with today's Groupon for two hours of bowling. Choose between the following options:

• For $35, you get two hours of bowling and shoe rental for up to six people at Jupiter Lanes in Jupiter (a $71 value).
• For $35, you get two hours of bowling and shoe rental for up to six people at Saint Lucie Lanes in Port St. Lucie (a $71 value).

Sister bowling centers Jupiter Lanes and Saint Lucie Lanes engage in heated sibling rivalry as each woos customers with bowling, billiards, full-service dining, a sports bar, and a tropical tiki bar. Imposing 12-feet-tall video screens play sporting events and music videos as bowlers skid across lanes in freshly sprayed bowling shoes ($3.50 each, $21 for six people). Two hours of bowling wears down the arms of ball-throwers, similar to escorting a panther on a neighborhood walk (a $50 value). Night owls and unsupervised cacti can keep late hours, with both alleys open until 2 a.m. on weekends, capping off an evening of activity with burgers, wings, dogs, pizzas, and fries at the on-site restaurant, which also has a full bar.
