Narrative:

I was flying VFR from ZZZ to ZZZ1 and then over to ZZZ2 and back to ZZZ. At the time there was a temporary flight restr area north of this area. At the time of flight I felt that I was well clear of the area, but after further review of the exact location of the facility (it's not marked on the VFR chart) (I found a graphic on the internet) I may have touched the outside boundary when I crossed over the ZZZ2 airport. Again at the time of the flight I felt I was well clear of the area. This was not intentional.
