Prepaid calling cards

[Russ Irwin]

I've spent a couple of hours on the internet searching for prepaid calling cards, and which might be
best, but I can't find any really useful information. All I'm really looking for is which prepaid
cards can be used to call back home (to the U.S.) from Spain. So I figure I'll just ask the the
experts here <grin> who have already traveled the Camino, and are from the U.S.

Thanks in advance for any help,
Russ
