Ever wanted to learn how to rex, jam and dance on roller skates but missed the ‘80s? Roller dance is back at Roller Odyssey, 2425 S. Pacific Hwy. Medford. Wednesday nights, from 6:30 until 8 p.m., skaters of all levels learn how to do the moves made famous by the disco craze and then some. It’s fun, it’s aerobic, it’s retro and it’s only $7 a class. For more information view the class schedule at www.sk8info.com or email Cheryl@sk8info.com.
