“If you’re west of the Rockies, call toll-free 1-800-618-8255. If you’re east of the Rockies, call toll-free 1-800-825-5033. First-time callers, call 775-727-1222. For the Wild Card line, call 775-727-1295.”
Most radio talk shows have just one number. That’s not the case with the king of late night talk, Art Bell. Why does the Art Bell show have so many different phone numbers? What number do you call if you’re not west of the Rockies, or east of the Rockies, but rather IN the Rockies?
That would be “The Second- or Third-time callers within 75 statute miles of the Continental Divide and who Prefer to Order their Mountain Dew with very little ice and/or Have Been Abducted by a Green or Grey alien within the past solar year Line, (775) 727-5550.”
Someone asked Art this once, and he said you could call either number.
Of course the more pressing question is what any self-respecting Doper is doing listening to Art Bell. 
Semi-Serious guess #1:
Because he’s trying to work against the Illuminated Conspiracy of Grand Master Far-Viewers: no-one knows what line he’ll choose, ('cept the claryvoyants) so the Martian assassin time-travellers won’t be able to interfere with the calls.*
Semi-Serious guess #2:
It makes it easier to for government operatives to trace your call so that they can send xeno-biological hyperspacial terrorists to assassinate those who KNOW The Truth! Ever wonder where Bell went those two times he disappeared? THEY took him and now he works for THEM!
Serious guess:
Because it tallies where his callers are from so he can sell demographic numbers to his advertisers…and government agencies who want to SILENCE those who know The Truth!.
Fenris
Seriously: he spent a half hour on Friday (…or Saturday) screaming about how “they” were trying to silence him 'cause he was having phone-line problems*
**Because when I get up at 4:30 he’s the only thing on and music’ll put me back to sleep. Him and his stooge George Nori force me to get up, if only through rising blood pressure.
