Upcoming Meeting

Hello CAT Members,

It is unfortunate but due to the public health concerns regarding the corona virus outbreak the CAT Board and meeting hosts have decided that the best course of action is to cancel the upcoming April meeting in San Francisco.  Anyone that has already registered will receive a full refund.  This meeting will likely be pushed forward to spring of 2021.  Everyone stay healthy.
