Be glad we dont have this to go through here(yet) This was a weed inspection that we had to go through on the Mcgrew trail in oregon last year. The guy reached around every nook and cranny looking for dirt and weeds. We all passed because we had cleaned up spotlessly but in years past people had been denied access due to small amounts of "imported soils" being found on their rigs.
The same rules and regulations that are applied to foreign species of plants should be applied at our borders. I guess they already are. But, ya know what I'm sayin...
