Also goes straight through Las Vegas. Alternatively, they could take I-15 north once they hit it and go through SLC, Boise, and then on to Portland and Seattle. They could also take I-84 west out of SLC and head to San Francisco (though that's not a direct route by any means). I-70 will put you pretty much right into a route to any of the major cities on the West Coast.
IF this is a credible sighting, this guy should be able to provide good IDs (i.e., facial hair, length of hair, clothing), and stuff like that. This should be publicized because both I-70 and I-15 are huge trucking lanes. Tell all the truckers to be on the lookout for two mid-eastern looking guys driving a car with out of state plates (if they drove from NY), and put the same info up at major rest stops and truck stops all along I-15. It would be pathetically easy to give every UHP and CHP officer a stack of 15 BOLO signs and have them hit every reststop on their route. You'd have the whole state covered in 5 hours.
Then just sit back and wait for these dirt muffins to walz into a truck stop to take a self righteous pee.
Ms. England could only dream of being a 300lb convict jacked up on amphetamines, prison porn, and a bad divorce.
What would the jihadists do when they get to the Sloson cutoff?
If I was that Adam Perlmen guy, I'd be watching my neck about now.
