u/EelsEverywhere

Going by what I experienced last year with Verizon (and I've seen similar complaints about AT&T), cell phone coverage can get really dicey at the fairpark, especially at the Lake Stage for some reason, and doubly-especially as the day wears on and more people arrive. Even with bars, service can slow to a crawl, and at points later in the day I had no service at all in the big crowds.

So, don't forget to have a muster point to gather at after sets - designate a place where you and your friends can find each other when you get split up!
