SOUND OFF: Where's the Worst Cell Phone Reception?

All this talk about the iPhone 5 has us thinking — sometimes, regardless of how wonderful a new phone may be, it still can't get past dead spots.

We all know the areas we avoid when we want to have an uninterrupted cell phone call. 

So, tell us: which cell phone network do you have, and where do you lose service? Please make sure to include the town or city, along with the street/area so we know where to avoid!
