The Missouri Department of Conservation,
http://www.mdc.mo.gov/,establishes hunting regulations, manages public grounds, etc.
You can actually hunt without taking a hunter's education course -just purchase the "Apprentice Hunter Authorization Permit."
http://www.mdc.mo.gov/regs/permits.htmHowever, you must hunt with a licensed(i.e. someone that has taken the hunter ed class) adultatleast 21 years old.
The MDC also maintains a database ofMDC-owned public property. For most hunting, you do not need to signin or call in advance.
