biking in massachusetts

I'm VERY new to biking and I'm looking for some good road and off road trails for new bikers in the massachusetts metro-west area.

thanks!!

I'm in Medford. Am a roadie only. For trail I understand the Fells is good riding. It's in my area (1.5 mi up the road). Also Charles River Wheelmen does group rides all around here, mostly road. Lots of women, couples, etc... all different levels. Go to http://www.crw.org

Spazzdog thanks for the reply. I just visited the site and it's great!

If you are looking for rail trails, I like the Nashua River Rail Trail that starts in Ayer which is just up 495. The Blackstone River Rail trail is also pretty nice but shorter and just over the line in RI. Go to massbike.org and you can look up the various trails and places to ride. It gives a description and usually a map. The sevenhillswheelmen.org also has group rides you can join, starting at level D (easy) and ****'s easy rider group C rides easycrider.com
