25-May-2003 -- After traveling about 120km east of San Luis R.C., Sonora we stopped off the highway at the closest to the confluence. Long story short we got stuck in the sand and it took all day, 3 police/highway patrol cruisers, a semi, a tow truck, a Bronco, a taxi and on foot. This confluence is only accessible with a 4x4 or off-road vehicle. The sand is too soft. I am planning to re-attempt within the next year with the proper equipment. It reached a dry 102F during the peak.
