My best friend is in Tennessee selling alarms.  He works every day until dark, so 9-9:30.
His birthday is on Saturday, I sent him an e-card, but he's alone, not having much success, and kind of frustrated.  His sister and brother in law are out there with him, selling...but I don't know them. 
I want to do something to let him know that I'm thinking of him, you know?  I'm broke, and don't have a lot of time to plan, but if anyone has any long-distance birthday ideas, please let me know.
 
Oh, I DID make him give me the sister's phone number, so I can get her in on the idea, but I'm at a loss.
 
Thanks for any ideas.
