Narrative:
I realized I was missing en route chart 19-20. Using chart 25-26, only part of V72 was shown. I assumed, incorrectly, that it was direct from leb VOR to cam VOR, and using the radial shown for cam, tracked the opp radial out of leb. I noticed that cam was deflected way to the left, but I thought it was because of low altitude. As time went on, I realized this was not the case and initiated a turn to intercept. I estimate I was about 8 NM north of the arwy.
