Many states have specific rules on what roadkill you can claim. One of those states has made it completely illegal to take home animals you find along the road.
After a long day at work, I'm trying to get home at 10 o'clock at night and the traffic light gets stuck on red. Can you run a red light legally in Texas?
If you go through any state's law book, you're going to find some very strange laws that are just plain weird but still enforceable no matter how ridiculous.
