David Bernstein recently noted Illinois State Senator Barack Obama's 1999 proposal for a federal law against licensed firearms dealers operating within five miles of a school or park. Every town I've ever visisted which has more than a few dozen inhabitants has either a school or a park. Hypothesizing that the ban would apply to city parks (e.g., Central Park in New York City) but not to National Parks, pick a geographical region, and describe where a licensed firearms dealer could operate. Or pick a geographic point (e.g, Houston)and identify how far a peson would have to drive in order to get to the closest point where a gun store could legally be located.
