Hi Deeno,
Have a great trip!
Drop me an email or give me a phone call on 02 9457 9049 and I can
provide some U.S. contacts for you that can assist with observing in the
Southwest.
Certainly there are opportunities to hook you up with friends in West Texas
near Fort Davis in the shadow of the McDonald Observatory including a friend
with a 48" (no, that is not a misprint).
There is also absolutely no way I could let you enter New Mexico without
first telling you that you absolutely must get to Chaco Culture National Historical Park,
home of the Chaco Canyon. This site was one of many inhabited by the
Anasazi people and is one of the best preserved archaeological sites within
all of North America. The Anasazi had a long connection with observing the
sky and you will see that in the architecture and petroglyphs, including one
depicting the supernova of 1054. See

There is also an observatory open to the public at the visitors center and includes
some serious aperture such as a 25" Dob. Friend John Sefick was one of the
founders of the observatory and often spends time there.

Whatever time you have allocated for the Southwest, it will never be enough.
In fact it might be best to call me and have pen and paper ready as there are so
many sites to see in that region like Canyon de Chelly that are so astounding
that it would be criminal to pass them by.
Best Regards
Gary
P.S.
if passing through El Paso in South West Texas, which is the gateway
down to Fort Davis, recommend you currently avoid the day trip across into
the border town of Juarez in Mexico due to the currently well reported
phenomenally high amount of drug cartel war related violence with over 2,250
deaths alone this year.

Unfortunately things don't sound much better in the Mexican border town of Ojinaga
either, with the army having to patrol the streets, so day trips across the entire
border there in the Southwest are probably best left to safer times.
