Did you exchange contact information?
Are the feelings mutual?
What exactly is your question regarding this situation?

No - did not get any contact info. Had to leave in a rush. Yes, feelings were mutual. Just have a name and a photo. Has anyone ever had same situation or found someone with just that info?

Have you tried Facebook?

"Has anyone ever had same situation or found someone with just that info?"

Yes. There were a few times I could kick myself for not exchanging information.

Justwantfair brought up a good suggestion. Try Facebook.

Did you find out anything about him like where he lives that might help narrow down where to look?

Did he get any of your information so that he might be looking for you?

I am going to caution you to be careful and think very carefully about trying to find him. Some people do take the Vegas slogan of 'what happens in Vegas stays in Vegas' literally. Try not to forget to live your life while you look. You may find him, you may not. If you do find him, he not be the person you think he is.

What u think

If you know his name, ( will assume if you talked you know where he is from) so with a name and a general city, you should be able to narrow it down

Depending on the name, it might be easy to reverse call his phone though paying at some websites that offer that product, but that is only if you believe that he would actually LIKE you to call him. I don't know how you buys were to each other but come on, we're talking about Vegas, maybe whatever happens there he might want to leave there, if not he might have exchanged some sort of recontacting information. Ah, also, with the product mentioned above, there is a chance the party who got looked up might feel EXTREMELY harassed. Like I said, if you think he actually wanted to keep talking to you then go for it, if not, there will be other guys to penetrate your mind. Maybe even some that give you info so that you can contact them at a later date :)

Good Luck,

Javi
