What is TC/R/NR? Oak Park residents get a discount on park district programs and Teen Center Members save even more! Therefore, if you live in Oak Park, you'll always pay the "R" rate, unless you are a Teen Center member in which you get the lowest rate. Even if you don't live in Oak Park, you might still qualify for the resident rate though! We co-op with other agencies to offer some of our trips and programs. Therefore, if you live in neighboring towns like River Forest, Berwyn, or Forest Park, you may qualify for the resident rate. Contact Melissa to find out for sure.
