10 Things to do for $10 this weekend, October 8-9, 2010

We get it, you've been saving up all month for your Mad Max Halloween costume and you're a little short on cash. That's okay, don't worry. You can still get out and have fun this weekend -- especially if your idea of fun includes building sandcastles, black comedies, dancing or culture. Build-a-Bike at Derailer Bicycle Collective (Friday, Free) Summer might be over, but Denver's abundant sunshine means even throughout the winter months the streets are often dry enough to ride on. The best way to keep away the winter doldrums is to get out and exercise, and a self-built bicycle is a great mode of transport. Keep in mind it takes two weeks to complete a bike, so don't plan on hitting the streets quite yet. Talking of the Dead and Dead Ringers at the MacSpa (Friday-Saturday, Free) You missed the opening reception and party on Thursday, but it doesn't mean you can't check out the Ouiji board-inspired artworks over the weekend. It's October after all, and there's no better way to celebrate Halloween than a toe-dipping into the occult. Black Sheep Friday at MCA Denver (Friday, $5+) Black Sheep Friday is always filled with completely random but always fun events. This week will not only include music from Littles Paia, but also sandcastle-building in the elevator. The Watching Hour: Fright Night at Starz Filmcenter (Friday and Saturday, $9.25) It's October, which can only mean one thing: horror movies. If you're not interested in the shock-and-awe of most modern films, you might want to make your way down to the Starz FilmCenter for the black-comedy-horror romp that is Fright Night. Light Rail Flash Mob Dance Party at Dave and Busters (Friday, free) For most people, it doesn't matter where they're partying, as long as they're partying hard. Some people want to spice it up a little, though. If you're in this group, you'll likely find solace in a flash mob dance party on the LightRail -- all it'll cost you is train fare. If nothing else, it's at least a safe way to get around. Clue at the Esquire (Friday-Saturday $7.25) It's a little bizarre to think a board game could have spawned a movie, but alas, it happened -- and it was pretty damn enjoyable. The classic whodunit film featured the likes of Tim Curry, Christopher Lloyd and more. Fresh City Life: Thriller! Dance Class at the Denver Central Library (Saturday, Free) If you've always wanted to learn the dance moves featured in Michael Jackson's "Thriller" video but didn't know where to start, now's your chance. You'll need to register ahead of time, but once you do, the class is free. You'll be well on your way to impressing your friends with your knee-wobbling and arm-crossing in no time. Larimer Sidewalk Arts Festival at the Meadowlark (Saturday, Free) Kids are always left out of the street-party scene in Denver -- or rather, they were always left out -- until the creation of Larimer Sidewalk Arts Festival came around three years ago. Nowadays, they have the opportunity to perform, sell goods at the marketplace, mingle and learn from practicing artists. La Ofrenda de los Muertos: Honoring the Days of the Dead at the Longmont Museum and Cultural Center (Saturday, Free) The art style of Día de los Muertos has always been a strong part of Colorado's culture, but that doesn't mean people totally understand it. In an effort to coalesce and showcase the culture, the Longmont Museum and Culture Center is hosting a month-long exhibit that opens today. Go for a hike (Sunday, Free) As we're getting deeper into October, the chances for outdoor activities not involving snow pants is getting less likely. What better way to celebrate the waning days of 60-degree weather than to go out and enjoy it?
