In May I am travelling from Mesa, AZ (Phx) to Anaheim, CA. I would like to maintain continuous contact with my father in Mesa who has a pretty powerful base in Mesa. I've been researching Win System and CalZona. I'm monitoring Win System but I haven't used it bcuz I don't if there's a required fee. I will say this, Win System is awesome, there was a you man on it Friday from Great Britain. If anybody can tell me about these two systems it would be appreciated.
