As a professional one always trys to keep abrest in their field.  CPE's in this industry are sorta been there done that and bought the t shirt.  Like cold is on the right hot on the left and s___t runs down hill.   The only way the waste water orginazations and supply stores can expect to draw a crown is to offer CPE's  and if you have to sit through these boring presentations to recieve a contact hour it is a waste of time.  Consider the expense of a "convention" you just comnpound the waste.   If you want infromation on a process or product hope you can use the internet and derive all the information you need.  I would strongly suggest that we drop this requirement.  It just irritates me rather than providing the desired education.
