Marcie:
Will be interested in your report from the falls and your impression of guide. If this works well for you, we would like to do same thing as one day trip down to PoP.
Wendy, all phone transmisions can be tapped, this includes faxes. However, it really takes advanced knowledge to do something. That is why people do fax credit card information. There are also secure faxes available that use encryption, if you want. But need to have same encryption on both ends.
