are there any problem with that?

A while ago, I asked if I can fly to LA from Austin, but I don't want to risk myself too much, so I was thinking about driving there with my cousin, who is legal, but someone suggested me that I can take GreyHound to get to LA.

Do any of you guys know about that?
I heard there is really really small possibility that we can be stop at check point around El paso area(on the way back to Austin from LA) and be searched....

and another question is... in order to get a ticket for greyhound.. do we need an id for that?

also, one really big question...

do we get stop and be searched at the El Paso????

Thanks alot...

Please answer this post.. really urgent matter....

p.s.
oh, by the way, I'm an asian, looking not that dangerous.. haha
