We shouldn't have to show papers simply because we exist. Everybody's got to exist somewhere. That is no reason for suspicion. If the feds must have interior checkpoints 100 miles deep built willy nilly over the states' jurisdiction and sovereignty, where's the limit? How far into our land is too far?
I should love our Canadian friends posting in this discussion so vehemently, with not a checkpoint in sight in their great white northern interior.
