Holy smokes! This is one of the absolutely coolest things I've gotten to do in Chicago. O.J. is an amazing artist & animator. His artwork of the city is wonderful, whether on the page or on the screen. And his knowledge of the city is awe-inspiring... he really loves Chi-town. I learned so much about the city, its history, places around town, etc. Got to learn about color theory & how just a slight shift in colors can make a picture appear completely different. To say I learned a lot is a woeful understatement! O.J. is friendly, easy-going, & has great sense of humor. If you want a truly unique experience while you are in Chicago, then you should definitely book this experience with O.J. And, if you have mobility issues (I'm currently using a rolling walker), O.J. has got you covered with a cool freight elevator up to his studio. Big thanks to O.J. for such a fun experience.
