I also have Verizon and have service in all the previously mentioned places, and always have great service at Slough Creek Campground. Never thought that would happen.

I use Verizon and have always had excellent service at Old Faithful, Canyon, Mammoth. Sometimes (not always) I have service at Norris, and one time I actually received a call while driving through Firehole Canyon (near the exit to Firehole Canyon Drive).

Then I do not get service again until I am almost to I-90 outside of Butte. Haven't tried it in Mammoth. It is a pay-as-you-go service so you can buy just what you think you will need for the trip, but it does not give me reception throughout the Park. _______________________________________________ Geysers mailing list Geysers at lists.wallawalla.edu -------------- next part -------------- An HTML attachment was scrubbed...
