don't take this the wrong way....but what's the point?
you seem to have a distance and time goal, but nothing else?
route is chosen simply to cover ground? in that case, why
not just spend the time on an indoor trainer? save the
trouble and expense of all those hotels!

what's the point of going cross-country other than to say
you did it? especially if more than half is simply spinning
the pedals through boring, dull, monotonous nothingness?

why not pick a bunch of interesting sights and make a big
loop, which just might total 3000km since that number
seems so significant?

sure, start in reno. cross nevada to utah, north to idaho
montana and wyoming before it gets too cold, then south
through colorado to new mexico. cross arizona, thru death
valley, and back to california.

your pictures that you'll show off after will be so much more
interesting....death valley, grand canyon, salt lake, sturgis,
los alamos, organ pipe, etc.

sure beats the heck out of:
....and here's a dead armidillo.
....and here's another dead armadillo.
....oh, and hey....here's an armadillo.
