One thing I can say...the hikers I've seen at Cosby are for the most part the serious type - not the typical tourist driving up from G'burg. I know exactly what you mean about Road Prong - at the crossings, you begin to feel like an exhibit at the zoo. My oldest loves that stream - however, she got in an argument with one obnoxious guy last year - this idiot didn't think any fish lived in there, which my daughter promptly disproved by catching a small trout. Then, he had the gaul to say "well, is that all that's in there - tiny fish?". I know it takes all types, but I'm glad I was upstream and out of earshot of all this - I don't have much patience with that amount of stupidity.
