Grandkids come, boating on the Potomac

Our 3 grandkids came for the weekend. Took them out on the pontoon boat around the creek and the Potomac. Also trial of my jellyfish barrier. It worked but not 100%. At least the kids were able to swim and play in the water while the adults monitored the area with a fish net for any wayward jellies that snuck in. We still scooped out about 20 over a 3 hour time but outside the barrier there were 100s floating about. Dash one of our grands still got stung.
