Chicago is the city I call home, and for good reason. I thought it would be appropriate to include some of my favorite pictures I've taken of the city.

A group of tall buildings against a blue sky seen from street level. Trees branches and leaves along the bottom of the image, with some people's faces being visible in the bottom left. A yellow boat on the Chicago river surrounded by skyscrapers (specifically trump tower to the right and the jewler's building to the left) as the sun sets in the distance. The chicago river as seen from the Wabash street bridge. A riverwalk with trees and benches can be seen from the right. Immediately down the river are Wendella's at trump tower in the wrigley building, with 4 boats being docket. It is nigh time and the top of the Wrigley building is showing blue and red for the colors of the American flag. A yellow boat sits docked at Ping Tom Park in Chicago's Chinatown. In the background, the Amtrak railroad bridge (former Pennsylvania railroad bridge) can be seen; it is the only vertical lift bridge in Chicago. The skyline of Chicago as seen from the south branch of the Chicago river. The sears tower sits front and center. In the foreground is an American flag, as this shot was taken on the back of a boat. The skyline of Chicago as seen from the Chicago river basin (area just before the locks connecting it to lake Michigan). In the center of the shot is the St. Regis (tallest building in the world with the lead architect being a woman) and off to the right is trump tower. The sunrise over lake Michigan as seen from the Chicago river basin. Off to the left is Navy Pier and its ferris wheel. In the foreground can be seen the front guardrails of a yellow boat, where the shot was taken from. The skyline of Chicago as seen from the breakwall by the lighthouse. Various famous buildings can be seen, including the Sears tower, the John Hancock building, the St. Regis, trump tower, and Big Stan (the standard oil building). The nothern skyline of Chicago as seen form the Chicago river basin. The John Hancock building and the Navy Piero ferris wheel can be seen. The sunset contains many warm colors, such as orange. All buildings in the shot with lights have the pride colors displayed, as it was taken during pride month.
