Moving a planted tank?

Any suggestions?  I've got a 38 gallon heavily planted tank with Crypts,
Anubias, Bacopa, and Hygro from my old apartment to my new one about 20
minutes away.  I imagine the best thing to do is not remove the plants from
the gravel, just remove 90% of the water and spray the plants with tank water
in an atomizer while my buddy drives.

Any suggestions?
