This is the best link I could find. As long as you had it prior to Apr 15th you will be fine. My wife still needs to get hers but she thinks she this change is ok. She can do it on her own time, not bother anyone, and actually learn something as she doesn't know a lot about boating.
I still think rip off and still think it will be a gong show all year at the boat launch just like before boat licenses.
