Couple of weeks ago we were heade to redwood. National forest from Grants Pas Oregon.
Ag check ahead, ok I fall into line with everyone else,multiple lanes,cars trucks,other rv,s. Everyone pauses about thirty seconds and moves on. Normal right?
....

I have never been to an Ag check point, except for being asked about fruit crossing to and from Canada.

I would assume stopping at an Ag check point would involve an inspection of the interior of a vehicle / trailer like a camper, as it would be common to carry some fruit in a camper (at least, we usually have some).

You "understand and tolerate them"... but you were surprised at a request to inspect the interior of your camper? What is the point of just asking if there are fruits and veg on board?

Related question... if it is common at these Ag check points to just wave vehicles through, or just ask about fruit and veg without an inspection, what is the point of them?

And another related question... with these "wave through inspection" stations, have they ever caught and/or stopped any bugs?

As I said, I know very little about this Ag inspection stuff.
