I parked my bike to the rack and went to the Lincoln Park Zoo. By the time I came back to the bike rack around 5:20pm, the bike was gone. The bike rack is surrounded by bushes and I didn't notice any surveillance cameras facing the bike rack. There were 2 bikes to the right of mine when I first parked it there. Both of those bikes were locked with cable locks, and 1 bike to the left of mine (my friend's bike), was locked with U-lock and cable on the seat. When I came back at around 5:20pm, all bikes with cable locks were gone. My friend still had their bike. A larger, rusty, black bike with a rack and rear/front fenders (unlocked) took the place of the 2 bikes that were originally to the right of my parked bike. 3 other bikes (a red Schwinn, a cobalt-blue Schwinn, and another bike of which I forgot the image of) were locked with U-locks to the rack. Because I simply locked it to the bike rack, the cable was most likely cut with a wire cutter and taken away. The right lever doesn't brake, and the left lever brake doesn't release itself from the front wheel after braking so I have to loosen it up after I brake. Whoever ends up riding that bike should be careful and keep track of the rear brake. Because the frame is very plain and solid white, it can very easily be painted over in another color or pattern. The rubber handle grips are also a bit white from sunscreen that I used earlier, so the grips won't be entirely black but more of a darker gray or faded black.
