Here's a sure sign the season has changed: Conner Prairie Interactive History Park (13400 Allisonville Rd., Fishers), Indiana's only Smithsonian affiliate, begins its outdoor season with an Opening Weekend celebration on Saturday and Sunday. This will be a chance for everyone to sample the new daily programs, like Historic Crime Scene Investigation, Frontier Survivor and Taste the Paste, that Connor Prairie is introducing this year. And, weather permitting, the 1859 Balloon Voyage will be back for its second season. Guests can soar 350 feet above the prairie for an additional fee. Opening weekend takes place Saturday, March 27, 10 a.m.-5 p.m. and Sunday, March 28, 11 a.m.-5 p.m. Admission is $13 for adults; $12 seniors; $9 youth. It's free for members and kids under 2.
