The other big event at this meeting was the first trial run of our wireless headphone experiment for members who's hearing is not a acute as it once was.  The equipment was purchased from and proved to be very successful.  So much so that we will be ordering more sets so that more members can take advantage of the technology.

Two headphones and the transmitter are only $29.26 plus shipping.  The transmitter plugged easily into our P.A. amplifier and with only a bit of fiddling we were up to speed.
