For a good central location of state laws related to firearms check this website, http://www.usacarry.com/info_explain...resources.html
Mouse over Resources and select the second option, Permit Info by State. Most writeups contain an indication of whether the state restricts carry in or around schools or if you can carry during pickup or dropoff. Almost all these discussions give the citation for the state's gun laws regarding concealed and, usually, open carry of firearms.
On the Idaho section there is also a pamphlet which outlines the Idaho Gun Laws. Look for the thread titled Idaho Gun Pamphlet on the Idaho page here for our situation.
Good Luck on your project!
