Narrative:

While on VFR flight from kansas city international to bridgewater, va, it was discovered after further review that I may have entered the north edge of restr area R3403A. Sectionals were not available at the airport from which I departed. I was using WAC charts cg-21 which are printed on a smaller scale than I am used to using. Looking at the map and using a visual line of sight it looked like I would avoid the restr area. Upon further review and drawing a line on the map, it looked as if I may have gone into the restr area 5-6 mi on the north end.
