Well, I got a TON of emails from my uni's club. They've been trying to get a collection of routes for some time, and next year's president (who lives in my building) has been putting together a booklet thing for new members of routes of 25-75 miles.

I'm actually in Cleveland, so I have to go pretty far out to find roads. I did in fact play with Google, which is how I found the bike trails. One of the local clubs also has maps online, with varying degrees of legibility. They're just not routes I'm comfortable with at my current skill level.
