Unless you’re a racoon or a dumpster diver, you probably don’t spend a lot of time exploring alleyways. But a casual stroll through the other side of your neighborhood can make for some fun sightseeing. You might discover secret gardens, adorable patios, or garage murals that you never knew existed. This weekend, Christian Huelsman of Minneapolis Alley Initiative for Neighborhood Stimulation will lead a guided bike tour of some of the public art to be found in Whittier, Lyndale, Powderhorn, and Phillips alleyways. This ride will be a relatively chill one, accessible to most levels, covering around 10 miles. Come with a bike and a helmet; you can sign up at www.brownpapertickets.com.
