I have lost signal in between tall buildings in downtowns. Lack of a clear view of the sky can do that. And I can't recover until my GPS has clear signal from at least five or six satalites.
Parts of downtown Chicago have an elevated train, I think same with NY. I have lost signal under those in Chicago.
