That's exactly where it was. It was in the lot at South and Pennsylvania. My wife ran in a 10k Saturday and after the start, I walked my kids down to the Subway there at South and Penn. Cut through that parking lot - and there it was. I did notice the work going on there immediately west of Banker's Life. Looks like big doings!
I saw you talkin about 10/22s and .22 ARs.
The rifle I was shooting the dueling tree with was a 10/22, with Blackhawk stock and hi-vis sights.
I also have a S&W 15-22 rifle. For the cost of the upper you were talking about, you can get a whole rifle.
If i go down there again, you're welcome to try them.
