Does anyone has any experience or route suggestion?

Two routes I've used:

Northern: Your choice of routes to Iowa City and then to southern
Wyoming. Follow I 80 across southern Wyoming; terrain is around 7000
msl but relatively flat; easy flying. Then via Helena and Missoula,
Montana, and west to Seattle. Then down the coast (or inland) to
Hayward.

Southern: Your choice of routes to Iowa City and then to Las Vegas,
New Mexico. Then to Winslow, see the meteor carter; follow the Grand
Canyon(buy a Grand Canyon chart) down to Kingman, Arizona, and
Needles, California; west to Bakersfield, then up to Hayward. (That
last leg is pretty boring.)
