I've seen more small gun shows than large...and more than I could count.
There's one every week end..at least one. Gun shows are a favorite way to raise money for your organization, here in Idaho. If you want to skip the BGC...take it out to the parking lot~
Idaho's only laws regarding selling guns and ammo:
Idaho Code Ann. § 18-3302A: May not sell to a minor without written consent of parent or guardian, or to anyone who is prohibited by federal law from owning firearms.
Idaho Code Ann. § 18-3308: May not transfer ammunition to anyone under the age of 16.
Idaho Code Ann. § 18-8505: It is a felony to knowingly transfer a firearm to a gang member.
