Prepaid Phone Cards what works! Goldendale

[Robert Wilson]

I've just about given up on carrying a cellphone in the US.  A calling
card for wireline has been the best for roaming travel through the US.
Are there any "prepaid CELLphone cards" that now offer "somewhat"
universal US coverage?  Is there a better way to do it, or should I just
stick with gas station payphones for now.  Our spare phone that I will
take is an analog cell.

Thanks, Robert
