"Experimental planes will still be a huge part of that airport.
... The ISC said it will not operate the same weekend as the
Arlington Fly-In (which draws 50,000 visitors each year)... also,
even under FAA rules for restricting airspace during a NASCAR
event, planes can still take off and land, they just can’t
fly over the stadium."

Mary Swenson, speaking to the Snohomish Business Journal about the
possibility of building a NASCAR track right next to the Arlington
Municipal Airport (WA). Marysville city leaders support the idea.
Arlington's elected officials, however, have taken more of a
wait-and-see attitude toward the concept.
