In all, seven states have laws that allow concealed guns on campus, though the details vary on who can carry where. Twenty states still ban carrying a concealed weapon on a college campus, and 23 states leave the decision up to individual colleges.This is all touchy-feelie, but in the actual event ... you still can't carry guns on campus in Oregon .. even though State Law allows it.
WARNING: I know I've posted this information before; more than once. I'll post it again, just in case someobody hasn't yet heard how Univiersities (at least in Oregon, and probably in other states), unilaterally and arbitrarily abridge the law.
I worked at Oregon State University (one of those "20 states") and the laws have no effect, because college and universities are a law unto themselves.
They will NOT allow anyone to carry on campus, regardless of the status of the CHL holder.
