Fernbank Museum

Confined to plutonium-powered DeLoreans and unwieldy telephone booths, time travel is a dangerous and mischief-baiting activity. Instead, let history repeat itself as often as you can stand it with today’s Groupon: $42 gets two adults and up to four children or grandchildren (under 18) a yearlong family membership to the Fernbank Museum of Natural History (an $85 value). Individuals can purchase solo museum membership, including admission and member benefits for one person, for $30 (a $60 value).
