That depends upon what you (and your neighbors) call a
"campfire." A small open-air fire in a pit (no more than 3' wide),
distant from a tree line or overhead combustibles (like tree
branches) for the purpose of cooking hot dogs and marshmallows is
probably all right. However, upon the complaint of a neighbor or
even a passerby, we are required to investigate and possibly order
the fire extinguished. Your best long-term option is to build on
outdoor barbeque or let your neighbors know your intentions.
