Sample Standardized Data: License Types
A data frame with 3 variables
License ID (numeric) (primary key) - Note that IDs can be stored as character, but this is less efficient.
License Type (character) ("hunt" = hunting license, "fish" = fishing license, "combo" = combination hunting/fishing license)
Duration in years (numeric) (1 = 1yr/short-term, 2 = 2yr,..., 99 = lifetime)
