Wow! Thanks for all the great advice! And the pictures defintely helped me get the point.
I have expanded my search somewhat to include the Specialized Sequoia - similar geometry to the Trek 1800C which allows more versatility in riding posture. Did a test ride on the Sequoia tonight and i was a dream. But after lugging my mountain bike around, any of these road bikes feels good!
I am still uncertain about the gearing issue. I ride in western Pennsylvania. Hills galore, poorly graded (at least the back roads).
One more issue - shifters, derailleurs. How much difference is there in the Shimano 105 vs. Shimano Ultegra. Worth spending the extra bucks?
