PA systems

[Stacey DeSpelder <37csp@pathwaynet.com>]

Saginaw Valley Region is in the market for a new public address system.  
Anyone care to give us some direction where to go and not go?  Several 
of our events are held at a local airport so our paddock is spread out 
parallel with the runway and our present two speaker system is 
inadequate.  Anyone have experience with wireless systems?  Thanks!
