Ahh, I finally got it! I had forgotten that the approach plate was updated and the frequency had changed at the airport that I was trying to land in. I also guess I just never had paid attention to the OMI lights when coming in for the approach. Thanks guys!

Another question though: In real world situations, when flying VFR, does one always fly on an NDB or VOR's radials? I know that you can use triangulation to make sure you're on the right track or near the area where you're supposed to be at a certain time, but if you're wanting to go from city to city where there is no VOR or NDB between the two cities, do you have to go out of the way to get to a waypoint to get onto another radial to then track you to your destination?
