Responded to your "new to the forum post" but also responding here for your convenience (and others who might find this thread first).
SCCA is a good source for finding tracks in your area:
SCCA Sports Car Club of America
As I mentioned on the other thread, the Central West and Midwest Division websites have links to most of the tracks in your area. Both Heartland Park Topeka and Mid-America (just south of Omaha) both have many open track DE days. Mid-America is a great DE track as it is very open and very safe.

Good luck and have fun with the new car.
