I didn't say no one who had any idea where they were going would take the Firebird turn-off, I said that no one who had any idea where they were going would likely take 347 --> Casa Blanca --> I-10 --> Riggs --> 347 --> (either Firebird or I-10). LOL
If I-10 were bad enough to justify that route, I think I'd just turn around and go back home!
