With 882 stations on 14 lines, Tokyo's amazing subway system is one of the largest -- and busiest -- in all the world.

It all had me more than a little nervous as I headed to Tokyo for a business trip.

For better or worse, the presidential campaign has kicked into high gear and both Barack Obama and John McCain are touting platforms covering everything from the economy to Iraq. We're disappointed to see neither candidate considers transportation a top-tier issue.
