Fantastic MBTA voyages

FutureMBTA There are fantasy baseball and football teams, so why not fantasy MBTA routes? The Future MBTA has posted ideas from readers for subway lines that will probably never be built in anyone's lifetime. The most impressive idea posted so far involves two urban rings that intersect near the South Bay shopping center. As long as it's play money, why limit yourself?

Note: The Future MBTA site was tagged by SHIFT Boston, a three-month-old blog on urban design here and around the world. Check out its fantasy view of the Rose Kennedy Greenway here.
