One man is helping to fight cancer, one beer at a time.

Todd Ruggere is having his own "Mass Beer Tour," drinking a Sam Adams in every community in Massachusetts (except the dry towns, of course) to raise money for Dana Farber/Jimmy Fund. He's visited dozens of towns already.

And on Saturday at 4 p.m., he'll be at Rolf's in North Andover.

It won't be easy visiting 351 places, but the beer might make it less stressful. So head down to Rolf's Saturday and wish him luck.

You can check his progress at http://351beers.tumblr.com/ or on his Facebook page. You can also follow him on Twitter.
