LG VX-8000

I'm in Continental Airlines Arena watching a Devils hockey game and I have full bars on my phone. However when I try to make a call the phone won't connect no matter how many times i dial/redial. It also won't receive any. My brother is with me at the game and he has an older model lg phone with verizon and i ask him to make a call to see if it's just me. He's able to make/receive calls. So i tell him to call my phone and my phone does not ring and he says it goes straight to voicemail. This seems to happen in certain areas..this happening to be East Rutherford. When I get home my phone is working just fine. Anyone else have this kind of problem?

thanks
