Something else to worry about this Fourth of July. It seems that some people have turned tennis balls into a fireworks filled, exploding bomb. If you have a dog or kids who like to pick up the frequently lost tennis ball while in a park or on a walk, this is the year you might want to check that ball. I haven't heard that this is an issue in the St. Louis area, but then, I'm always late to fads.
The balls often have some duct tape covering the split in the ball where the explosive was put in and there is a fuse of some sort sticking out.
Home grown fireworks are the worst in my opinion. Every neighborhood has people who shoot off their own fireworks beginning well ahead of the 4th and continuing on for several days after. When it's a dry weather time we get concerning about grass fires or even roof fires due to these things dropping down in populated areas. Then it's the constant noise which really scares many dogs to the point they have to be sedated.
Folks, just go to an organized and controlled fireworks display, please don't do your own for the sake of everyone around you.
