Interskate 91, Hadley

At Interskate 91, time-travel is possible—at least on Thursday nights. That's when the roller-rink's retro dance party sends skaters rolling to tunes from the '80s and '90s, kicking off an eight-wheeled trip down memory lane. Meanwhile those who prefer to look forward to the future can do battle in the laser-tag course, practicing for a not-too-distant future in which humanity's greatest enemy will be highly-distractible space cats.
