Celebrations continue all weekend and include a parade, a buckaroo breakfast and live music at the historic Belfry. Don't miss this wild ride. 7 pm, Sisters Rodeo Grounds, 220 W. Cascade Ave., Sisters. $14-$32.
THEATRE—A murder mystery involving a British sex specialist and time travel? Cascade Theatrical Company's intimate cast, directed by Deb De Grosse and assistant directors Jane Williamson and Richard Frazier, is sure to keep you on the edge of your seat. "Communicating Doors," written by Alan Ayckbourn, is an intricate time traveling comic thriller by the British master of farcical comedy that delighted London and New York audiences alike, and is bound to please Bend audiences as well. 7:30 pm. CTC Main Stage, 148 NW Greenwood Ave. $12-$19.
SMASH 'EM—While your dad may be the person who taught you how to repair cars, watching cars smashed to smithereens can be equally bonding. What better place to yell, over the roar of engines and the crunching metal, "I love you, Dad!" 1-5 pm. Deschutes County Fair & Expo, Redmond. $15.
Summer Shootout Marble Tournament
MARBLES—Before Pogs, Beanie Babies and Pokémon cards, kids collected marbles. Simultaneously game pieces and a form of playground currency, these tiny glass balls—and a child's skill in amassing them—carried legitimate social cache. Whether you're an old pro or you've never played, it's time to dust off your cats' eyes for some friendly competition (not to mention, some sweet prizes). 10 am-2 pm. Des Chutes Historical Museum, 129 NW Idaho Ave. Free.
JUG BAND—They may not have washboard abs, but members of the blues-rock (dare we say, "postmodern jugband") outfit Sassparilla can often be found with an actual washboard hanging in front of their abs. Strike that. With music this high energy, we'd be surprised if they didn't all have a ripped core. It's like some Amish kids got tatted up and started a punk band during their Rumspringa. 8 pm. The Belfry, 302 E. Main St., Sisters. $8.
Sweeney Todd: The Demon Barber of Fleet Street
THEATRE—2nd Street Theatre presents this gory, dark but fascinating play based on the book by Hugh Wheeler. After luring his victims into his barber's chair, Sweeney Todd takes revenge by killing them and having his willing accomplice, Mrs. Lovett, bake them into her meat pies. Original music and lyrics by Stephen Sondheim bring audiences into the sick recesses of Sweeney Todd's mind. 3 pm, 2nd Street Theatre. $19-$22.
ROCK—What do you get when a group of former Mormons (including one Osmond) take to the road with their collective melancholy and a van full of musical instruments? Members of indie rock band Desert Noises has been figuring that out, taking lessons from the road and lives left behind while drawing inspiration from dreams. The band comes to town as part of the McMenamins Great Northwest Music Tour. 7 pm. Old St. Francis, St. Luke's Room, 700 NW Bond St. Free.
Astronaut Richard Richards
ROCKETS—While Richard Richards may have a bone to pick with his parents for their name selection, he doesn't seem to begrudge that they set him in front of a TV to watch the Apollo moon landing. A former Navy pilot, Richard Richards went on to four trips to space in the Space Shuttle. In Bend on a lecture tour. 6 pm. Bend Library, 601 NW Wall. Free.
BEER WALK—There are two ways to enjoy this event (well, really, more than that): There is the beer geek approach, to sample beers from Oblivion, Bridge 99 and Deschutes and their unique selection of hops. Or, there is simply just drinking beer and listening to the bands, like Wilderness and The Rum and The Sea. Either way, we think you'll make out all right. 4-10 pm. Old Mill District. $20.
Author! Author! with Geraldine Brooks
BOOKS—Pulitzer Prize winner and New York Times bestseller Geraldine Brooks began her writing career as a journalist, eventually working as a foreign correspondent for the Wall Street Journal. Many of her books have been inspired by her reporting; her most recent, "Caleb's Crossing," is inspired by the life of the first Native American to graduate from Harvard. 7 pm.
