 You have to be at least 12 years old to use fireworks on the 4th in West Fargo. And as the 4th approaches, medical professionals preparing for what they say is their busiest time of the year. One of the ways you can help is by donating blood. With more people on the roads and lakes, there tend to be more accidents and injuries, so there's a greater need for donated blood. Tomorrow is the last day to donate before the holiday at the DAC Men Blood Bank in Grand Forks.
