Hi. I'm planning to travel very soon from Pittsburgh to LA, and I need to get to my destination in about 3.5 days. I could extend this to 4.5 days, though, possibly...

Currently my scenario is basically to go through the interstates and make the following stops:

Pittsburgh to Louisville (1/2 day)

Louisville to Oklahoma City (full day)

Oklahoma City to Gallup, NM (full day)

Gallup to Los Angeles (full day)

A few questions:

Is my timetable feasible?
Do you recommend driving along Rt. 66 part of the way -- or any other scenic byways that won't slow me down too much?

If I did make it 4.5 days, would anyone be kind enough to suggest a rough revised itinerary--especially a scenic one?

Thank you very much.
