Fireworks Illegal to Possess?

I grew up in Minnesota where fireworks were illegal, so I have never really been into, or cared much about fireworks. The ones you can buy are usually lame and expensive, so I have never bought any. In North Dakota Fireworks are legal and have just recently started going up for sale. I just read this:

FARGO – Police here have issued a reminder to residents that it is illegal to possess, sell or use fireworks within the city limits.

WTF? So if I was to buy some fireworks to shoot off out in the country on the 4th I couldn’t bring them home? Where would I put them? I totally see not being able to sell or shoot off fireworks in town, but it’s illegal to just possess them in town too? I see how they would be illegal to possess them in Minnesota, but not in North Dakota where they are legal. So if you buy fireworks, make sure you don’t drive through town with them. I hate stupid laws that make no sense and can’t be enforced.
