I'm on the April 18 ORD-ONT mileage run that's been widely publicized on this site:

One of the strengths of this run is that is 7 segments, starting at 9 (not 6, or 7!). Now, I'm looking for run on miles that really zig-zags me around the UA/US route map in a day, like:

ORD-DFW-DEN-SEA-SFO-IAD-ORD

Any suggestions?
