It is a burden on local businesses. We have been spending part of our winter about half way between Palm Springs and LA. Our Sunday routine takes us to the local airport for breakfast. A great little mom and pop operation that is very popular with locals and visiting aircraft. One beautiful Sunday morning a couple of years ago, we went and the place was dead. No visiting aircraft. When I asked why, the answer was Obama is arriving in Palm Springs and all the airspace within about 30 miles is shut down, even where we were on the other side of the mountains.
