I get what you're saying, however, after attending Austin City limits Music Festival, where at any given time there can he 70K or more people in attendance, trying to find my wife, who was watching a different band at a different stage then me, can be a struggle to meet back up. (Especially after the band is finished and people start shuffling to the next stage for another band.)

It's also very confusing for a person who isn't very direction savvy. For this reason alone, I'm definitely going to look into these compasses.
