December 11, 2012By

By Don Jewell Cards and Letters It happens every year and it is an emotional rollercoaster.  It generally starts a couple of weeks before Thanksgiving and continues until just after New Years – and it is simply heartbreaking.

The history of GNSS shows each year has always been more successful than the year prior, and in 2013 we expect the trend to continue.
