Letter from Grand Canyon Postmaster L. L. Ferrall to Carl Hayden regarding the proposed national park bill. Ferrall states that nearly all those who live in the canyon are against it as it gives a monopoly to the railway and hopes that the bill does not start "a war" for Arizona.

During 2008, 2,105 adult arrestees participated in the AARIN study. Participants completed the survey instrument and provided a valid urine specimen for testing. In addition to the core AARIN instrument, a supplemental set of question was asked of the arrestees. This Market and Use Addendum consisted of a series of questions related to the arrestees’ acquisition of drugs and specific drug market behaviors.
