Welcome to the area, I'm just over the boarder in Michigan by 7 miles and a member out at Young's longshot. For me, matches are a 3-4 hour drive, but it used to be far worse.
The Bomber Run, in Madison, is having another regional match April 2nd. It's a fun match, I participated in both the Pro match, January regional and upcoming April 2nd regional.
You have Red brush in Newburgh that has regional matches (facebook group Red Brush Precision Rifle Challenge). Sign ups are on practiscore.com
IL PRSC in Waterman IL is having a couple PRS regional matches and "lost boys" matches this year (search for Illinois Precision Rifle Steel Challenge on facebook for more info).
Wisconsin has both Regional and a Pro match near Cascade WI
Michigan matches are at Marksmanship Training Center north of Lake City, these will be regional only this year.
Both MI and WI match info can be found at
https://www.prschallenge.com/ as well Facebook.
In past years there were matches in Ohio but I haven't seen info on any of those recently. Big Dog Steel and Rayner's Range were the two doing them.
I know there are several guys from the indy area, you might want to hit up the Red Brush facebook page and introduce yourself and find a travel/training buddy.
