After closing in on my route with the satellite shot, I do see that the road curves away from my path in some of the areas where I was missing caches. Because the caches were all roadside, I had only set the radius at .3k. After changing that to 1K, I received all but 2 of the caches. Those I still can't figure out, but I am a lot closer to correcting my problem now. Thank you so much for taking the time to help out and "point me in the right direction" (or should I say "put me back on track")!!
Happy Caching!
