Needles, NV?

The city of Needles, CA, located on I-40 right on the Arizona border, is considered seceding from California and becoming part of Nevada:

NEEDLES, Calif. - The city of Needles wants to leave California for neighboring Nevada - or maybe just form its own county.

The City Council earlier this month told staff to look into two scenarios: having the city to become a part of Nevada, which is just a few miles away, or staying in California but withdrawing from San Bernardino County and forming a county of its own. Needles is just across the Colorado River from Arizona, about 30 miles north of Lake Havasu City.

Councilman Roy Mills says secession would require approval from Congress, both states and a popular vote.
The city of 5,700 is 213 miles from its county seat, and officials have had strained relations with county supervisors since March. They claim the county's been unwilling to help keep the city's troubled hospital open as a full-service medical center.

The county says it offered $1.5 million to keep some services open but the city rejected it.

I can't blame them. I'd secede from California if I could.

If I were them I'd take the Nevada option. That way they can build casinos and won't have to get one of those fake Indian tribes to sponsor them like they do in California.
