C172 charter in LA

A little tape on the N number ought to solve that.

You mean to alter or cover the N number? No. it won't work. SMO is a
towered airport. According to my knowledge from the SMO guys...the fee
is collected for every time wheels tough the ground. A person sitting
in a pickup truck with radio watches whether the plane is tough the
ground on the runway. Therefore, it is free for go-around but if you
stay in pattern for 3 touch and goes, then you pay 3X landing fee.
There is no fee for home based aircrafts and flight school, only the
outsiders.
