Good point, and yet another aspect of her disappearance that just rankles - the location is so remote, there are no towns or local LE stations nearby (it took over 2 hours for LE to respond to RT's 911 call IIRC), there are no Media Outlets, it's in a different state (CA) than where she lives in AZ, and CA has the largest population of any state in the US, and San Bernardino County is the largest county in CA with lots of crime and people going missing all the time.
"California has been the most populous state in the United States officially... [the] current population is estimated at 39,536,653 as of July 1, 2017, by the U.S. Census Bureau."
Which State Has the Biggest Population?
The population of San Bernardino County is over 2 million people
San Bernardino County, CA | Data USA, and the Sheriffs Office investigating BT's disappearance has jurisdiction for the entire County.
Even Needles, CA, the closest city, is over an hour away, and with a population of 4,800 people, has 17 recent 'mapped' crimes on SBSCO webpage:

I can't think of a more tricky geographical or jurisdictional scenario under which to investigate a missing person case. Especially a person who just disappeared within minutes of walking with her husband and returning to their RV on a desolate desert highway with no witnesses. There's just no information it seems to help pinpoint what happened to her easily. It's altogether mind boggling.
Kudos to SBCSO for conducting their investigation under these difficult circumstances.
Bumping for Barbara, desperately hoping she will be found soon!
MOO
