I guess one thing left for you to do is the beach, which is OK for a while, and parks like Lincoln Park where there is a Zoo and a nice 19th century Greenhouse/conservatory.
.. What would I do, if I were there now? I would go to Greek town, or China/Vietnamtown (on the north side), find some cheap place to eat, or maybe some Mexican Restaurants in Logan Square. If it were Thursday or a weekend I_d find the _Reader_, newspaper and see whats up around town... I would also go down to UIC (University of Illinois at Chicago) and check the job listings and also maybe over to Fontano_s for a sub. (See? I mention some things to do, and three are eating!)
If you are 15, I imagine you won_t have much money with you to spend, so maybe head to Old Town and shop a little bit in the Psychedelic shops, -what is left of them anyway since the 60_s-, or to Newtown, north up by Belmont and Broadway and find some used book shops...
Near Lincoln and Fullerton You_ll find the old Biograph Theater where Dillinger was shot dead, and also near there are also some used book shops...
