I might think they were shadowy Federal black-ops intent on assassinating me, and not police.
BTW, state highways crossing national forests, not sure those are "Federal lands", I think the State owns the right-of-ways for them. I can say for sure they are patrolled by the State Patrol here in Oregon. BLM rangers don't pull people over for speeding, their old green trucks are not set up for that.
