Just discovered two informative websites about rail trails. Thanks to Tim Jones, outdoor columnist with the Nashua Telegraph, for mentioning www.traillink.com in a Telegraph article today. There's detailed information about some of the trails and limited information on others. But the rider reviews seem to be quite helpful and there's more useful info here than anything else I've been able to find on the internet so far.
Also discovered www.nashuacitystation.com/trails.php which focuses on recreational rail trails of southern New Hampshire. This site has fewer details, but it looks like a good starting point and has links to some of the rail trail websites.
Do you have any favorite biking trails to share? Be sure to submit a comment and let us know.
