So good to hear from you, Angie!
I sure hope your community wasn't impacted too much by those horrible tornadoes!
I think your caterpillar is Erannis tiliaria/linden looper. The pictures on the internet show it with an orange head, but I notice yours has just molted - many cats lack their coloring for a few hours or more after molting.

Thanks Sherry. I do believe you have pegged the little critter. Hmmm....now what to do about them. They are eating my trees up.
My community was devestated by the tornadoes. I posted a video link at the "bandjzmom please check in" thread. Thanks for the ID.~~Angie
