As you might well imagine fireworks use in the listening area is up this year with the availability of fireworks for sale. Law enforcement officials say there have been plenty of calls for service involving fireworks concerns. Marshalltown Police Chief Michael Tupper says if you have concerns call the law enforcement center at 641-754- 5725 and police will investigate as they are able. Today and tonight will be busy times. Pet owners and those who are disturbed by fireworks are urged to stay indoors as much as possible, run the air conditioner or fan or t-v, music or the radio to drown out the noise. Fireworks outlets that have opened up report brisk business. Officials with the Fire Department in Marshalltown say they are hopeful for no fire calls or fireworks injury calls during this time frame.
