Does anybody know if Verizon encrypt the radio transmission between your phone and the tower on all the calls you make?

Verizon does not encrypt your calls so watch what you say. If you want a secure network get GSM service

If your phone is in analog mode then its entirely reasonable to assume that your conversion could be received by someone using a cheap [unlocked] 800mhz scanner. I have had analog calls on my cell phone where my conversation was mixed in with someone else's, persumably the same cell tower as me - if I could hear them then I'm sure they could hear me.
If your phone is in digital (CDMA) mode then it would take a scanner that is expensive and not readilly available to the public to intercept your conversion.

Analog can be heard by other devices, too. Any technical person with a basic spectrum analyzer can listen in. A technician, engineer, or even a ham radio buff can amuse themself that way. We sometimes did it for troubleshooting purposes. Trust me, you don't want to do this in bad areas of a city. Listening to, uh, 'working girls' discuss their job is NOT entertaining.
I did catch my boss goofing off one time, though. 
CDMA is, for all practical purposes, uncrackable (at present). Unless you are the NSA, FBI, or CIA, you aren't going to crack it. And if you ARE them, you don't need to. You get a warrant and take the audio off at the switch.
Pretty much the same for GSM, though GSM has been cracked at a university. In theory, CDMA is several orders of magnitude harder to crack than GSM.
In practice, I wouldn't worry about it.
Of course, if you are calling a land line, your call is no more secure than any land line call, which is to say, not very secure.

Who to believe... a long intelligent post or "Verizon does not encrypt your calls so watch what you say. If you want a secure network get GSM service" ... I wonder! :p

Sometimes yes, sometimes no. It's an interesting and weird phenomenon called "FM capture". Once in a while, you can even wind up in an unplanned conference call with people you don't know!
Strictly an analog phenomenon.
