I got home a bit ago from dove hunting in the Delta and passed about 8 different MHP vehicles at different times between Grenada and Madison county all headed north on I55. All were hauling tail with lights blazing. One was a truck towing a flatbead with some kind of boxy looking machine on the back. Couldn’t really catch a good glimpse in low light and trying not to wreck. Was wondering what was going on but seeing that made it seem out of the ordinary.
