I wasn’t saying it was fright or wrong only that they exist all over the US about 100 miles inland. I’ve driven through them many times. I’ve had dogs sniff my car as i went through them.
It’s not surprising that if people are taking large amounts of weed through these checkpoints that they are stopped.
I’ve made it a point to plan my travel around avoiding them, it would be smart for people growing weed to do the same until it’s federally uncriminalized.
