Just a question from an average to below average fly fisherman...

I'm wondering what everyone's opinion is regarding prime lies that are on the side of a stream that is fished often or are subject to frequent encounters with people. Do trout tend to "permanently" avoid these feeding stations because of the frequent proximity to humans? It seems like when I catch a trout, it is always on the other side of the stream or in the center. I'm sure I spook my fair share of fish, but I try to be careful; so that is what prompted this question.

Thanks in advance for any comments!
