Upcoming naturalist/ranger programs/events?

Last year on during our visit we found several park ranger events at the state parks that we attended. These were great for the family. They were informative about the local nature and FREE. I found these programs within the forums last year, but have not seen any this year. I may be looking in the wrong area.

Does anyone have any info for this?
We will be in Sowal on Thursday and were looking forward to more of these small programs.
