Thanks everyone for the advice!
We're a very small-town library (population about 3000) so Cycling Plus wasn't really an option. (Cost was $61 for a year...a bit too much for us.) The director fell in love with the name 'Dirt Rag' and felt the magazine's title and looks would help attract younger readers, so we've sent for the free issue.
If we don't like what we see, I'll be back looking again....I'm tempted by Adventure Cycling, myself....
