great first chapter! Your style of writing makes it realistic as if I was right there watching the events. I am doing a similar story and try to be descriptive myself for the same reasons. My only comment about how to possibly improve it would be to give a little more description about the city of Chicago. Maybe add other landmarks in relation to the ones you use (the park and the bar) so the reader can get a mental image of the city layout even if they've never been there? I look forward to reading more and finding out what happens to Kasey and Paige!
