All the concern is humoring as the FAA is launching an App. This way few have excuse since apps fix all! Ignorance of the law need not be, less your a terrorist as you don't really care:

FAA Launches Smartphone App To Help UAV Users
The FAA is launching a beta version of a new smartphone
application designed for use by UAV users.
The application, called B4UFly, is aimed at model aircraft
users and is designed to give them information about restrictions
and requirements in effect at their current or planned
Many UAV users have little or no aviation experience, and some
fly the UAVs where they can pose a danger to manned aircraft.
B4UFly will give fliers the knowledge to operate safely, FAA said.
For example, the app determines restrictions or requirements
in effect where they want to fly. It gives the user a status icon
that considers airspace, proximity to airports, temporary flight
restrictions, current law and other FAA guidance and procedures.
It also gives information on the parameters that drive the
status indicator, a “Planner Mode” for future flights in different
locations, interactive maps with filtering options, and links to
other FAA unmanned aircraft systems resources and regulatory
information, FAA says.
Operators of model aircraft that fly within 5 mi. of an airport
are required by law to notify the airport and the air traffic control
tower, if there is one at the airport, before operating the model
aircraft, it said.
FAA is working on an electronic notification process to satisfy the
requirement that will become part of a future version of the app.
During the beta test, FAA will collect feedback and operational
data from users to develop the electronic notification process, it
FAA Administrator Michael Huerta announced the initiative
in May and asked for volunteers to test the app. Those who have
already signed up will receive the app soon.
The beta testing is expected to last several months. FAA then
plans to make B4UFLY available to the general public. The beta
testing will only be available for iOS devices at first, but FAA is
working on a version that will also be compatible with Android
