What major cities are separated by 20 min. - 45 min. but form separate metro area's? (state, size)

[MDAllstar]

I was thinking about different metro area's and how they are divided. San Francisco & Oakland, Minneapolis & St. Paul, Dallas & Fort Worth, and NewYork & Newark form one metro area. What major cities are next to each other but are technically different metro MSA's? Which ones are close to becoming one MSA?

San Francisco and San Jose - 40 minutes apart, continuous dense urban development between - but separate metro areas.

Isn't the 2010 census data coming out at the end of this month? C.D. will go wild on that day.

Raleigh-Durham.

L.A. and San Bernardino

Hartford, CT and Springfield, MA, major enough in their own states and decently sized metros.

Orlando and Daytona Beach.
The cities are probably more than an hour apart, but the metro areas border each other.

Tampa & St Pete. Colorado Springs and Denver will eventually be there.
