The first man from the future who traveled to the past starved in the absence of nutrient-rich mini ice-cream balls. Take a safe trip back in time with today's Groupon. For $35, you get a household membership, five one-day guest passes, and a magazine subscription (a $75 total value) to the Hennepin History Museum, located inside a Renaissance and English Gothic mansion.

The Hennepin History Museum houses artifacts from the historical history of Hennepin County. In addition to free admission for your entire household, the household membership ($50 value) includes access to the galleries and library, discounts on tickets to special museum events, a 10% discount in the store, as well as advance invitations to all openings (see sidebar for details.) You'll also receive five one-day guest passes (normally $5 each) to let out-of-town guests explore current exhibits such as Icons for the Bereaved. The exhibit, running through May 20, showcases funereal artifacts and traces the evolution of mourning traditions from 1850 to present day.

Or explore The Century of the Child, a permanent exhibit that creates "time stations" that record the lives of children growing up in the area. A century's worth of change is manifested in old clothing, toys, and relics from child labor and education. To keep up to date on Hennepin History Museum's frequently rotating exhibits, you'll receive a subscription to Hennepin History magazine with your membership. And since this membership includes free admission to Hennepin County historic sites such as the John H. Stevens House, there's more to see than the museum or the raccoon that's always leaving cryptic messages on the museum's typewriters.
